Uni-T UT501A 1000V Insulation Resistance Tester
UT501 100V-1000V Insulation Resistance Meter Ground Tester
UT500 series insulation testers are used to measure the insulation resistance of electrical equipment and household appliances. This is done by measuring the insulation resistance between electrical circuits or between circuits and ground. UT500 series can measure insulation resistance, AC Voltage, low resistance, PI (Polarization Index) and DAR (Dielectric Absorption). These are ideal tools for ensuring transformers, generators, high voltage motors, power capacitors, power cables, arresters and other electrical equipment that can operate in a safe and accurate manner.
