UNI-T UT505B Handheld Insulation Resistance Tester

UNI-T UT505B Handheld Insulation Resistance Tester

Digital multimeter and insulation resistance tester functions are combined in the UT505B series of portable true RMS insulation resistance testers. These meters can detect insulation resistance, PI, DAR, and automatically compute resistance ratio to ascertain the insulation state in addition to the standard multimeter operations.
