Kewtech KEW3128 Kyoritsu Data Logging 12KV High Voltage Insulation Tester

Product details:

Use this high voltage insulation tester to analyse the insulation of cables, transformers, generators, high pressure switches, insulators and wiring installations.

The Kewtech KEW3128 has 6 test voltage ranges: 500V, 1000V,2500V, 5000V, 10000V and 12000V. This gives the tester maximum insulation resistance range of up to 35T? and makes it fully suitable for use in a wide variety of high voltage installations.

This insulation tester is ideal for logging insulation breakdown over a time period thanks to built-in data logging capabilities. Up to 43,000 individual records can be directly stored on the tester’s memory, complete with real-time insulation resistance/leakage current graphic representation with time and bargraph*.

Kewtech’s 3128 is designed to be powered directly from its built-in rechargeable battery or directly from mains AC power. It’s also made for use in tough environments and is IP64 rated when the lid is closed.

Additional functions of this unit include a print screen function for recording the display as a BMP image, filter function, leakage current/capacitance measurements, voltage/frequency measurements and automatic discharge after testing to ensure your safety at all times.

Key Features:

  • Suitable for use via rechargeable battery or can be directly powered from an AC line
  • Automatic discharge after testing with monitoring of discharge voltage
  • Very high short-circuit current up to 5mA speeds up testing of capacitive loads, with minimal charging times
  • Compliant with IEC 61010-1 CAT IV 600V for use in industrial applications
  • Live circuit warning by message on display and audible buzzer
  • IP64 rated (with lid closed) with drip and dust proof design
