The Digital Insulation Resistance Tester series have high performance, and safe configuration and improved electro circuit. It is one new item which has more fully function, higher precision and easier operation. It’s also one quakeproof, dustproof and damp-proof tester and can fit work environment of outdoor.

The output testing voltage can be changed between 100V/250V/500V/1000V/2500V/5000V for different item no. The resistance can reach 200GΩ; the tester also can measure alternating voltage.

This Tester apply for all kinds or electric equipment and insulation materials such as transformer, electromotor, cable, switch appliance, etc.It is a perfect electrical testing meter.
