Home Electrical Instruments 9.Electricity TesterUT500 Series Insulation Resistance Tester


UT502A Insulation Resistance Tester


UT501A series insulation resistance tester is mainly used to check the insulation resistance of electrical equipment, household appliances or electrical lines to the ground and phase to ensure that these equipment, electrical appliances and circuits work in a normal state to avoid accidents such as electric shock and equipment damage. This series integrates the measurement of functional parameters such as insulation resistance, AC voltage, CONTINUITY low resistance, PI polarization index and DAR insulation absorption ratio; it is measuring insulation resistance of transformer, transformer, generator, high voltage motor, power capacitor, power cable, lightning arrester, etc. Ideal test instrument.
