Description
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 the 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, capacitors, cables, arresters, and other electrical equipment can operate in a safe and accurate manner.
Models in UT500 series: UT501A, UT501B, UT502A
