UT500 series Digital Megger Meter insulation testers measure the insulation resistance of electrical equipment and household appliances by measuring the insulation resistance between electrical circuits or between circuits and the ground. The 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 safely and accurately.
