Digital insulation resistance tester, 250V 500V 1000V digital megohmmeter, automatic range from 0 to 2000 megohms, earth resistance tester with backlit LCD

[SAFE AND RELIABLE MEGA OHMMETER] Double insulated IEC-1010, overvoltage category II safety standard. When measuring rated voltage, if the measured resistance is less than 5M ohms, the measurement time should not exceed 10 seconds.
[ALARM PROMPT] In certain emergencies, the meter illuminates the red alarm indicator, emits an audible alarm, and also features a low battery indicator, an over-limit prompt, a high voltage prompt, etc.
[EASY OPERATION] The electrical tester has a large, high-definition LED display with a maximum display of 9999. It features automatic backlighting, which turns on automatically during measurement and off when measurement is complete. The reading can be clear even in dark environments.
[DATA LOCK] This stirrer locks the measurement data after measurement to prevent other interfering factors from affecting data changes. Median resistance: 250V, 500V: 100MΩ, 1000V: 1000MΩ. Resistance, on/off test: 0Ω ~2KΩ.
[WIDE APPLICATION] The insulation tester is suitable for measuring the insulation resistance of electrical equipment and insulating materials such as transformers, motors, cables, switches, electrical appliances, as well as for the maintenance, testing, and verification of various electrical equipment.
