UT505A - Insulation resistance tester by Uni-T

Description

The meter measures the insulation resistance of electrical and household appliances. This is done by measuring the insulation resistance between electrical circuits or between circuits and ground. The device can measure insulation resistance, AC and DC voltage, PI (Polarization Index) and DAR (Dielectric Absorption).

The meter is used to measure the insulation resistance of insulating materials and various types of electrical equipment such as transformers, electrical machines, cables, switches, electrical appliances, an ideal tool for electrical maintenance, testing and inspection.
