UT500 series insulation testers measure the insulation resistance of electrical equipment and household appliances, between circuits or between a circuit and ground. The UT500 series can measure insulation resistance, AC voltage, low resistance, PI (polarization index) and DAR (dielectric absorption ratio). They are ideal tools for making sure transformers, generators, high-voltage motors, capacitors, cables, surge arresters and other electrical equipment operate safely and correctly.
