UNI-T UT505 Series Handheld Insulation Resistance Testers
Product Overview and Specifications
Introduction
The UT505 series handheld true RMS insulation resistance testers combine features of a digital multimeter and an insulation resistance tester. Aside from typical multimeter functions, these meters can measure insulation resistance, PI, DAR, and automatically calculate resistance ratio to determine insulation status. The UT505 series is suitable for insulation resistance testing of precision tools, including motors, cables, transformers, switches, electrical appliances, and insulated materials.
Product Image Description
A red and grey UNI-T UT505A handheld insulation resistance tester is depicted. The device features a digital display showing "12 TEST 10.4 VDC" and "10.0 GΩ". Control buttons and a rotary dial are visible for function selection and operation. The meter includes ports labeled COM and EARTH, and is shown with connected red and black test leads.
