How Does It Compare with the JLab High Voltage Tester?
| Model | Test voltage | Accuracy | Other listed details |
|---|---|---|---|
| This insulation tester (EL-ARTVMCT-1240) | 100 V, 250 V, 500 V or 1000 V (types A to D) | ±5% | Transistorized, compact and portable; ranges 0–25 MΩ to 0–200 MΩ |
| High Voltage Insulation Break Down Tester | 2.5 kV and 5 kV (as listed) | ±2.5% | Mains operated; automatic short-circuit cut-off; for electrical plants and machines |
Choose this tester for everyday insulation checks on low-voltage wiring, appliances and small machines, and for teaching benches where a portable instrument is easier to handle; the high voltage model suits kilovolt testing of plant and machines.
What Is the Insulation Tester Used For?
An insulation tester applies a steady test voltage between a conductor and earth, or between two conductors, and reads the very small leakage current as a resistance in megohms. A high reading shows sound insulation; a low or falling reading points to damp, ageing or damaged insulation before it causes a fault or a shock. Typical jobs are checking wiring after installation, testing motor and transformer windings and cables, and checking appliances after repair; in ITI electrician and wireman trades and in diploma and engineering electrical labs, students practise these tests on wiring boards and machines.
As a general guide, the test voltage is chosen to suit the rated voltage of what is being tested: the lower voltages for low-voltage and electronic circuits, 500 V for ordinary mains wiring and appliances, and 1000 V for higher-rated equipment such as larger motors and cables. Always follow the standard or specification that applies to your work. Test only circuits that are switched off and isolated, disconnect sensitive electronics first, and let long cables and capacitive equipment discharge after the test before touching the conductors.
What to Specify When Ordering
- Type — (A) 100 V, (B) 250 V, (C) 500 V or (D) 1000 V; if you need more than one type, state the quantity of each.
- Power source, leads and carrying case — ask JLab to state these in the quotation, as the listing does not give them.
- Quantity — the minimum order is 10 units.
- Tender details — quote your tender reference and any test-voltage requirement it sets.
Frequently Asked Questions
Which type should I choose?
Match the test voltage to the equipment you will test. Types (A) and (B) share a 0–25 MΩ range at 100 V and 250 V; type (C) reads up to 100 MΩ at 500 V, and type (D) up to 200 MΩ at 1000 V.
How accurate is it?
The listing gives an accuracy of ±5% for all four types.
How does it differ from the High Voltage Insulation Break Down Tester?
This is a portable, transistorized tester for 100 V to 1000 V. The high voltage model is listed for 2.5 kV and 5 kV, is mains operated, has an automatic short-circuit cut-off and is listed at ±2.5%.
What powers it, and are test leads included?
Neither is stated in the listing. Ask JLab to confirm the power source and the accessories in the quotation.
What should an export enquiry include?
The type and quantity, the destination country and port or city, the delivery terms you prefer (for example FOB or CIF), any packing or labelling needs and the tender reference if there is one.
Who manufactures this insulation tester?
JLab (Jain Laboratory Instruments Pvt Ltd) makes it at its works in Ambala, Haryana, India, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, an electrical and physics lab instrument manufacturer in India, incorporated in 2017 and located on Hargolal Road, Ambala, Haryana. The insulation tester is produced at JLab’s own works instead of being bought from a trader, so institutions, dealers and importers buy factory-direct and repeat orders are handled by the maker. The company holds MSME Udyam registration UDYAM-HR-01-0003849 (manufacturing enterprise) and Importer-Exporter Code 3317504552. JLab exports worldwide and ships to buyers in every region — for example Hungary in Eastern Europe, Tunisia in North Africa, Lithuania in Northern Europe, Slovenia in Southern Europe and the Maldives in South Asia. For tenders, see the JLab lab tenders page.
