The complete electrical testing equipment list for engineers, contractors and procurement teams in Jordan: every instrument you need for LV installations, plant maintenance, MV substations, solar plants, calibration, telecom and labs, with what to look for in each. From EE Electronics, Amman.
In this guide
Key takeaways
- Build your electrical testing equipment list around the work you do, not around a catalogue. Seven job profiles cover almost every buyer in Jordan.
- Every list starts with the same core: a multimeter, a clamp meter, an insulation tester, an earth tester and a voltage detector, all with the right CAT safety rating.
- MV commissioning, solar plants, calibration labs and telecom networks each add a specialist layer on top of that core.
- Buy calibrated, genuine instruments with local support. A cheaper grey import with no calibration certificate is not accepted on most projects in Jordan.
Every electrical project in Jordan, from a villa in Amman to a 33 kV substation for a solar plant in Ma’an, depends on the same thing: measurements you can trust. Yet the electrical testing equipment list a team actually needs is rarely written down. Contractors buy what they used on the last job, maintenance teams inherit instruments nobody has calibrated for years, and procurement departments receive requests with a brand name and no specification.
This guide fixes that. EE Electronics, a supplier of test and measurement equipment in Jordan for more than 30 years, has organised the complete electrical testing equipment list by job profile. For each profile you will find the instruments to buy first, what each one is for, and what to check on the datasheet. Use it to plan a new toolkit, to audit the one you have, or to write a specification for a tender.
The electrical testing equipment list at a glance
Start by finding your profile in the table below. Most teams fit one or two rows; larger contractors and utilities cover several.
| Job profile | Typical work | Core instruments |
|---|---|---|
| Electricians and contractors | LV installations, fit-out, troubleshooting | Multimeter, clamp meter, installation tester, insulation tester, earth tester |
| Plant and facility maintenance | Factories, hospitals, malls, data centres | Thermal camera, power quality analyzer, 5 kV insulation tester, battery tester |
| MV/HV testing and commissioning | 11 kV, 33 kV and 132 kV networks and substations | VLF, tan delta, TTR, winding resistance, breaker analyzer, relay test set |
| Solar PV | Commissioning and O&M of PV plants | PV tester, IV curve tracer, irradiance meter, solar clamp meter |
| Calibration and metrology | Calibration labs, process plants, utilities | Multifunction, process, pressure and temperature calibrators |
| Telecom and data networks | Fibre and copper network builds | OTDR, fusion splicer, power meter, LAN certifier |
| Universities and R&D labs | Teaching, research and product development | Oscilloscopes, power supplies, signal generators, bench meters |
1. The core electrical testing toolkit for electricians and contractors
These instruments belong on every electrical testing equipment list, whatever else your team does. They cover verification of new LV installations, periodic inspection and day-to-day fault finding on 230/400 V systems.
| Instrument | What it is for | What to look for |
|---|---|---|
| Digital multimeter | Voltage, current, resistance, continuity | True RMS, CAT III 1000 V / CAT IV 600 V, low-impedance (LoZ) mode |
| Clamp meter | Load current without breaking the circuit | True RMS, AC/DC, inrush capture, flexible probe for large conductors |
| Insulation resistance tester | Insulation of cables, panels and motors up to 1 kV | 250/500/1000 V ranges, PI and DAR, auto-discharge |
| Earth resistance tester | Earth electrodes and grounding systems | 3-pole and 4-pole methods, stakeless clamp option, soil resistivity |
| Multifunction installation tester | Full verification of new installations | Loop impedance, RCD, insulation and continuity in one instrument |
| Portable appliance tester (PAT) | Safety testing of portable equipment | Auto test sequences, barcode and report download |
| Cable tracer and wire locator | Identifying cables and breakers, finding faults | Live and dead circuit tracing, depth estimation |
| Voltage detector | Proving dead before work | Rated for the system voltage, self-test function |
If your budget allows only one specialist instrument, a multifunction installation tester replaces several single-function testers and produces the test records consultants in Jordan ask for at handover. For deeper insulation work, see our guide on how to choose an insulation resistance tester.
Electrical Installation Testers
- Insulation, continuity, loop impedance and RCD tests in one unit
- Automatic test sequences and memory for test certificates
- The single most useful instrument for LV contractors
Understand CAT ratings before you buy
The measurement category (CAT) printed next to a meter’s terminals, defined in IEC 61010, tells you where in an installation the instrument is safe to use. The higher the category, the larger the voltage transient the meter can survive. It is the first thing to check on any handheld instrument.
| Category | Where it applies | What it means for you |
|---|---|---|
| CAT II | Plug-in loads: socket outlets, appliances, portable tools | Fine for appliance testing, not for distribution boards |
| CAT III | Fixed installation: distribution boards, busbars, motors, fixed wiring | Minimum for electricians working in panels |
| CAT IV | Origin of the installation: service entrance, main board, meters, outdoor overhead lines | Needed for work on main switchboards and utility connections |
A CAT IV meter used with CAT II test leads is only as safe as the leads. Replace damaged or unrated leads, probes and clips with ones rated at least as high as the instrument.
2. Plant and facility maintenance
Maintenance teams in factories, hospitals, hotels, malls and data centres need to find problems before they stop production or trip a critical supply. Their electrical testing equipment list adds predictive tools to the core toolkit.
| Instrument | What it is for | What to look for |
|---|---|---|
| Thermal imaging camera | Finding hot connections, overloads and imbalance in live panels | At least 160×120 pixels, radiometric images, reporting software |
| Power quality analyzer | Harmonics, imbalance, dips, swells and energy audits | Class A to IEC 61000-4-30, long-term logging |
| 5 kV insulation tester | Motors, generators and MV cables | PI, DAR, step-voltage and guard terminal |
| Battery tester | UPS and substation battery banks | Internal resistance, string testing, trend software |
| Vibration meter or analyzer | Bearing and alignment problems on motors and pumps | Velocity and acceleration, FFT on analyzers |
| Infrared thermometer | Quick spot checks between thermal surveys | Adjustable emissivity, distance-to-spot ratio |
| Environmental data logger | Temperature and humidity in switch rooms and data centres | Long battery life, alarms, cloud access |
| Lockout / tagout kit | Safe isolation before maintenance | Locks, hasps and breaker lockouts for your panels |
For most plants, the thermal camera and the power quality analyzer pay for themselves fastest: one prevented shutdown usually covers the cost. Our thermal imaging camera buying guide explains which resolution to choose for your panels.
3. MV/HV substation testing and commissioning
Jordan’s grid runs at 400 kV and 132 kV for transmission and 33 kV and 11 kV for distribution, with a growing number of private substations at solar plants, factories and large buildings. Testing and commissioning this equipment needs specialist instruments, usually owned by testing contractors, utilities and EPCs.
| Instrument | What it is for | What to look for |
|---|---|---|
| VLF cable test system | Withstand testing of MV cables | Peak output for your highest cable class (62 kV peak for 33 kV acceptance) |
| Tan delta tester | Insulation condition of cables, transformers and bushings | Sinusoidal VLF or power-frequency source |
| Partial discharge test system | Finding weak joints and terminations | Online and offline modes, fault location |
| Transformer turns ratio (TTR) tester | Ratio, polarity and vector group of transformers | Three-phase automatic testing |
| Winding resistance tester | Winding and tap changer condition | Test current suited to your transformer sizes |
| Circuit breaker analyzer | Timing, motion and contact resistance of breakers | Number of channels, motion transducers |
| CT/PT analyzer | Ratio, excitation and burden of instrument transformers | Knee-point testing, accuracy class assessment |
| Primary injection test set | Testing protection with real primary current | Output current and duty cycle |
| Protection relay test set | Relay commissioning and maintenance | Three-phase outputs, IEC 61850 support |
| SFRA | Mechanical integrity of transformer windings | Frequency range, comparison software |
| Oil BDV tester | Breakdown voltage of insulating oil | Automatic test to IEC 60156 and other standards |
| Cable fault locator | Finding the fault after a cable fails | TDR, surge generator and pinpointing |
Not every team needs all twelve. A cable jointing contractor needs the VLF, the insulation tester and a fault locator; a substation commissioning team needs the transformer, breaker and protection instruments. Our guide to VLF cable testing covers the test voltages used for Jordan’s 11 kV and 33 kV cables.

4. Solar PV testing
Jordan has built one of the largest solar fleets in the region, from rooftop systems to utility-scale plants. Commissioning and maintaining them follows IEC 62446-1, and the electrical testing equipment list for a solar team looks different from a building electrician’s.
| Instrument | What it is for | What to look for |
|---|---|---|
| Solar PV tester | IEC 62446-1 commissioning tests on strings | Open-circuit voltage, short-circuit current, insulation and polarity |
| IV curve tracer | String performance against the expected curve | Voltage and current range for your strings, irradiance sensor |
| Solar irradiance meter | Measuring irradiance during tests | Calibrated reference cell or pyranometer |
| Solar clamp meter | DC string current | DC current to 1000 A or more, 1500 V DC rating |
| Solar insulation tester | Insulation of arrays and DC cables | Test voltages up to 1000 V or more for 1500 V systems |
| Thermal camera for solar | Hot cells, bypass diodes and connectors | High resolution, low NETD, drone compatibility |
| Electroluminescence (EL) system | Micro-cracks and cell defects in modules | Portable night-time imaging |
| Ground fault string locator | Finding earth faults in large arrays | Non-intrusive tracing |
Teams that also commission the plant’s 33 kV collection system add the MV instruments from section 3, especially the VLF test set and the insulation tester.
5. Calibration and metrology
Every instrument on this list drifts over time, and every process plant depends on transmitters and gauges that must be checked. Calibration labs, utilities, pharmaceutical and food plants, and oil and gas facilities in Jordan use these instruments.
| Instrument | What it is for | What to look for |
|---|---|---|
| Multifunction calibrator | Calibrating multimeters, clamp meters and process instruments | Source and measure accuracy, ranges covered |
| Process calibrator | Field calibration of transmitters and loops | HART communication, documenting capability |
| Pressure calibrator | Pressure gauges, switches and transmitters | Pressure range, built-in pump, accuracy |
| Temperature calibrator | RTD and thermocouple simulation and measurement | Sensor types supported, resolution |
| Dry block calibrator | Calibrating temperature sensors | Temperature range, stability, inserts |
| Loop calibrator (4–20 mA) | Checking control loops | Source, simulate and measure modes, loop power |
| Electrical calibrator | Voltage, current and resistance reference | Accuracy class and traceability |
| Energy meter calibration system | Verifying revenue and sub-meters | Single or three-phase, reference accuracy |
Most manufacturers and quality systems recommend calibrating test instruments every 12 months. Add the calibration cost and the time the instrument is away to your budget, and ask for a calibration certificate with every new instrument.
6. Telecom and data network testing
Fibre-to-the-home rollouts, mobile backhaul and data centre builds keep fibre and copper network teams busy across Jordan. Their electrical testing equipment list is mostly optical.
| Instrument | What it is for | What to look for |
|---|---|---|
| OTDR | Locating faults, splices and losses along a fibre | Wavelengths, dynamic range, event mapping |
| Fusion splicer | Joining fibres | Core alignment for backbone work, splice time and battery life |
| Optical power meter | Measuring link loss with a light source | Wavelengths and connector adapters |
| Optical light source | Reference source for loss testing | Single-mode and multimode wavelengths |
| Fibre inspection microscope | Checking connector end-faces before mating | Automatic pass/fail analysis |
| LAN cable certifier | Certifying copper cabling to category standards | Cat 6A and above, certification reports |
| Network cable tester | Wire map and troubleshooting | PoE detection, length measurement |
| Industrial protocol tester | Modbus, Profibus, Profinet and CAN networks | Protocols supported, decoding |

7. Universities, training centres and R&D labs
Engineering faculties, vocational training centres and R&D teams in Jordan need bench instruments that are accurate, robust enough for students, and supported locally for years.
| Instrument | What it is for | What to look for |
|---|---|---|
| Oscilloscope | Viewing and measuring signals | Bandwidth, channels, protocol decoding |
| DC power supply | Powering circuits under test | Channels, voltage and current range, programmability |

| Training kits | Teaching electronics, automation and embedded systems | Curriculum, experiments included |
| Lab workstations | Safe, organised benches | ESD protection, power distribution |
Safety equipment and tools that complete every list
No electrical testing equipment list is complete without the equipment that keeps the person holding the instrument safe, and the tools that make the work possible.
- Safety: high voltage detectors, insulating gloves, arc flash protection kits, portable earthing sets, insulating mats and insulated hand tools.
- Tools: hydraulic crimping tools, cable cutting and stripping tools, torque wrenches for busbar connections, and label printers for clear identification.
- Accessories and consumables: lugs, glands, terminal blocks and tapes from our electrical accessories range.
How to build and budget your electrical testing equipment list
- List the tests you do every monthStart from the work, not the catalogue. Write down the tests your team performs regularly and the voltage levels involved.
- Separate must-have from occasionalBuy the instruments you use every week. For tests you need twice a year, renting or using a testing partner can be cheaper.
- Match the safety rating to the locationCheck CAT ratings and voltage ratings against the highest point in the system where the instrument will be used.
- Standardise on fewer platformsInstruments that share software, batteries and accessories cut training time and spare parts.
- Budget for the full lifeInclude calibration, spare leads, carrying cases and training, not only the purchase price.
| Priority | Instruments | Why |
|---|---|---|
| Buy first | Multimeter, clamp meter, voltage detector, 1 kV insulation tester, earth tester | Used every week |
| Buy next | Thermal camera, power quality analyzer, 5 kV insulation tester | Predictive maintenance |
| Rent or outsource | VLF, tan delta, relay and transformer test sets | Needed a few times a year |
Buying electrical testing equipment in Jordan
Where you buy matters as much as what you buy. Projects in Jordan, whether for a utility, a government tender, an international EPC or a private factory, increasingly ask for proof that test instruments are genuine, calibrated and supported.
- Genuine products: grey imports may lack a local warranty, carry the wrong plug or language, or be refused by consultants. Buy through a supplier that sources from the manufacturer or its authorised channel.
- Calibration certificates: ask for a calibration certificate with each instrument, and keep the recalibration date in your asset register.
- Datasheets and compliance: for tenders, request datasheets and a compliance statement against your specification with the quotation, so the evaluation is quick.
- Lead times: specialist MV and calibration instruments are often built to order. Ask for a delivery time in writing and plan purchases before a project’s commissioning phase.
- Local support: training, firmware updates, spare parts and repairs are much easier with a supplier in Amman than with an overseas web shop.

What equipment is used for electrical testing?
The core electrical testing equipment list is a digital multimeter, a clamp meter, an insulation resistance tester, an earth resistance tester, a voltage detector and, for installations, a multifunction installation tester. Maintenance, MV, solar, calibration and telecom teams add specialist instruments on top of that core.
What is the most important electrical testing instrument?
For most electricians it is a good True RMS multimeter with the right CAT rating, followed closely by a clamp meter and an insulation tester. For maintenance teams, a thermal imaging camera usually delivers the fastest return.
What CAT rating do I need for electrical testing equipment?
Use at least CAT III for work inside distribution boards and on fixed wiring, and CAT IV for main switchboards, service entrances and outdoor supply points. The test leads must carry the same rating as the instrument.
How often should electrical testing equipment be calibrated?
Every 12 months is the common interval, and sooner if an instrument has been dropped, damaged or gives unexpected readings. Ask for a calibration certificate when you buy.
Should I buy or rent MV testing equipment?
Buy the instruments you use every month. For tests you need only a few times a year, such as relay or transformer testing, renting or using a testing contractor is often more economical.
What test equipment do I need for solar PV commissioning in Jordan?
A solar PV tester for IEC 62446-1 tests, an IV curve tracer with an irradiance meter, a DC clamp meter, an insulation tester rated for the array voltage and a thermal camera. Plants with their own substations also need MV test equipment.
