UNI-T UT505 Series Handheld Insulation Resistance Testers

UT505 series handheld true RMS insulation resistance testers combine features of a digital multimeter and insulation resistance tester. Aside from the typical multimeter functions, these meters can also measure insulation resistance, PI, DAR, and automatically calculate resistance ratio to determine the insulation status.

Models in UT505 series: UT505A, UT505B
