UT501A Insulation Resistance Tester
Insulation resistance testers are mainly used to detect the insulation resistance of electrical equipment, household appliances or circuits to ground and between phases, to ensure that these equipment, appliances and circuits work properly and to avoid accidents such as electrocution, personal injury and equipment damage. This series integrates the measurement of insulation resistance, AC voltage, continuity low resistance, PI polarization index and DAR insulation absorption ratio and other functional parameters; it is the ideal test instrument for measuring the insulation resistance of transformers, mutual inductors, generators, high-voltage motors, power capacitors, power cables, lightning arresters and so on.
