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.
UT505 can be used in insulation resistance testing of precision tools, including motors, cables, transformers, switches, electrical appliances, and insulated materials.
The UNI-T UT505B Handheld Insulation Resistance Tester represents the pinnacle of portable electrical testing technology, providing professionals with an unprecedented combination of precision, intelligence, and diagnostic depth. Engineered to meet the most demanding electrical testing requirements, the UT505B transforms complex measurement challenges into clear, actionable insights.
