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 Ratio).
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. UT501B and UT502A meet IEC61557 standard.
Features
