Kewtech KEW3125B High Voltage Insulation Tester (5kV)
Introducing the Kewtech KEW3125B, the UK's smallest high-voltage insulation tester!
Portable and lightweight for on-site use, the KEW3125B gives high-voltage technicians and professionals, quick easy access to insulation resistance measurements with reliable, accurate results. This meter is ideal for performing cable and motor diagnostics, as well as for performing stable measurements in high-voltage substations.
The Kewtech KEW3125B has selectable test voltages of 500, 1000, 2500 and 5000V (5kV) and can perform insulation resistance measurements up to 1TΩ. A built-in diagnostics function can be used to perform dielectric absorption ratio (DAR) and polarisation index (PI) tests and a timed testing function is also available.
Weighing just 1.9kg (with the battery) and measuring just 177 x 226 x 100mm (L x W x D), the KEW3125B insulation resistance meter is easy to take from site to site. If you're fed up with heavier testers and looking for a lightweight solution that does everything you need, the KEW3125B is an excellent choice.
There are many extra benefits to the KEW3125B insulation resistance tester, including a lock-down test button, indication of output/discharge voltages, automatic discharge after testing, a voltage output warning system and a filter function to remove electrical noise, ensuring stable measurements at all times.
