KEW 3128 - High Voltage Insulation Tester

  • Microprocessor controlled high voltage insulation resistance tester with Diagnostic functions.
  • Suitable for analyzing the insulation characteristics of cables, transformers, motors, generators, high-pressure switches, insulators, wiring installations, etc.
  • 6 ranges: 500V, 1000V, 2500V, 5000V, 10000V, 12000V Fine adjustment of voltage setting at each range is also possible
  • Graphic representation of the insulation resistance and leakage current versus time on large display with bar graph and backlight.
  • Can be operated from built-in rechargeable battery or from AC line.
  • Automatic discharge after test with monitoring of the discharge voltage.
  • Internal memory can store about 43,000 data (max).
  • Robust design for field use with IP64 rating (with lid closed).
