| Kyoritsu 12 kV Digital High Voltage Insulation Tester 3128
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).
