UNI-T UT-502A 500V-2500V Digital Insulation Resistance Tester ,PI and DAR Measurement, Auto Resistivity Calculation UT-502A

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, genera-tors, high voltage motors, power capacitors, power cables, arresters and other electrical equipment that can operate in a safe and accurate manner.

Applications:
It is used for insulation resistance measurement for insulation materials and various kinds of electric equipments such as transformer, electric machines, cables, switches, electrical appliance, a ideal tool for electric maintenance, testing and inspection.
