Digital Insulation Resistance Tester with a Built-in High Power Voltage Generator

Encapsulated in a rugged and moulded plastic case, this high performance digital insulation resistance tester is an invaluable tool for field testing. The digital insulation resistance tester, model 803, measures alternating current and tests insulation resistance of up to 2000MΩ and voltage below 750V AC.

With a built-in high power voltage generator, the output testing voltage is adjustable via a rotating switch among 250V, 500V and 1000V depending on specific requirements. This well-designed tester offers a large backlit LCD screen making it ideally suitable for use under bright sunlight or in poorly lit environments.
