UNI-T UT512D high-voltage insulation resistance meter

The Uni-T UT512D is a digital high-voltage insulation resistance tester designed for demanding environments such as power generation, telecommunications and industry. The instrument offers four test voltage levels of 250 V, 500 V, 1000 V and 2500 V, allowing the measurement settings to be matched to the specific application. It supports polarization index (PI) and dielectric absorption ratio (DAR) measurements, which give a more detailed picture of insulation condition.

After a measurement, the test voltage is discharged automatically, reducing the risk of accidental contact with live voltage. A high-voltage alarm adds a further safety layer when working on electrical equipment.

Up to 999 measurement records can be stored and transferred to a computer via USB, making it easier to analyse results and document measurements during maintenance work.
