ZC11D-10 2500V Insulation Resistance Tester Meter (ZC11D-10)
2500VInsulationResistanceTesterMeterZC11D-10
●Description
Insulation Resistance Tester Meter ZC11D-10 is required in use away from magnetic fields placed horizontally. 2500V resistance megger megohmmeter is as insulating determination may be the ends of the analytes are connected respectively on the two terminals of the "Ground" and "Line". At rated speed rotating cranks, the resistance value can be measured. This ZC11D-10 insulation ohmmeter is applicable to measure the insulation resistance of motors, cables, transformers, electronic components, home appliances and other electrical devices, as well as insulation measurement of resistance wire strain gauges.
