Digital Insulation Resistance Tester Series

The digital insulation resistance testers, model 803, measure alternating current and test 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. Alternating current can be measured.

The tester series has a backlit LCD screen making it equally suitable for use under bright sunlight or in poorly lit environments. In addition, encapsulation within a rugged, molded plastic case, provides durability for these high performance digital insulation resistance testers.
