UNI-T UT505B Handheld Insulation Resistance Tester

UT505 Series Handheld Insulation Resistance Testers

The UT505 series are handheld tools that combine the features of a digital multimeter and an insulation resistance tester. In addition, these devices can measure insulation resistance, PI, and DAR. Furthermore, they automatically calculate the resistance ratio to check the insulation status.
