UNI-T UT501A Insulation Resistance Tester

UNI-T UT501A Insulation Resistance Tester
This product comes with a 3-year warranty. UT501A insulation resistance tester.
The UT500 series electrical insulation testers are used to measure the insulation resistance of electrical equipment and household appliances during regular inspections. This is done by measuring the insulation resistance between electrical circuits or between circuits and ground (equipment ground). The UT500 series can measure insulation resistance, AC voltage, low resistance, PI (polarization index), and DAR (dielectric absorption). The individual devices of the UT500 series differ from each other in their test voltage ranges (UT501A 100V to 1000V, UT501B 250V to 1000V, UT502A 500V to 2500V), maximum measured insulation resistance (UT501A 5G0Ω to 5GΩ, UT502A 0MΩ to 20GΩ), and other parameters.

These testing and inspection devices ensure the proper functioning of transformers, generators, high-voltage motors, power capacitors, power cables, arresters, circuit breakers, electrical machines, and appliances. They are ideal devices for performing electrical maintenance and are manufactured in accordance with IEC61010 and IEC61557 standards.
