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.
