GM-5K Insulation Resistance Meter is used for measuring resistance value of insulation materials, insulation resistance of transformer, motor, cable, electric equipments and etc. It’s widely used for power electric, posts, communications, mechanical and electrical installation and maintenance and relevant fields. 

♦  Multi measuring voltage range, the max. resistance is 2TΩ.

♦  Battery supply, insulation measuring range can be switched.

♦  LCD screen, easy to operate.

♦  The environmental temperature is testable.

♦  Auto timing, alarm to short start every 15 seconds.

♦  Auto calculating, the R15S, R60S, R600S, absorption ratio and polarizability index value could be stored automatically.

♦  Output short circuit current is large than 5mA, fast charging to the capacitive load.

♦  High anti-interference, stable and reliable.

♦  Full protection functions.

♦  Chargeable batteries, auto power off if low battery.
