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, capacitors, cables, arresters and other electrical equipment can operate in a safe and accurate manner.
UT501B is an excellent insulation resistance tester used for insulation resistance measurement for insulation materials and various kinds of electric equipment such as transformers, electric machines, cables, switches, and electrical appliances, an ideal tool for electric maintenance, testing, and inspection.
