KEW 3128 HIGH VOLTAGE 12000v INSULATION TESTER

Description

• 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).
