Digital insulation resistance tester, 100 V/250 V/500 V/1000 V, megohmmeter, ohmmeter, insulation megohmmeter, measuring range from 0 to 2000 mΩ

Automatic defrost function: Automatically defrosts after measurement, preventing any residual charge in the circuit from causing an electric shock.

Applications: This insulation resistance tester measures the insulation resistance of various electrical equipment and insulating materials, including motors, cables, switches, and household appliances. It is also used for the maintenance, testing, and verification of high-quality electrical equipment.

Wide measuring range: Rated test voltages: 100V/250V/500V/1000V, with a range up to 2000mΩ and AC voltage measurement capability. It can measure AC voltages up to 500V (full-scale linear indication).

The wide range and locking button make selection and use easy. Easy to use: The battery status indicator (the battery control light illuminates) also serves as a high voltage indicator for the megohmmeter. A low resistance beep alerts you.
