Uni-T UT511 High-Voltage Insulation Resistance Tester

Uni-T UT511 High-Voltage Insulation Resistance Tester The Uni-T UT511 High-Voltage Insulation Resistance Tester is the entry-level model in the UT510 series, designed for insulation measurements at voltages up to 1000 V and a range up to 10 GΩ. It is ideal for diagnosing electrical installations, motors, or medium-voltage equipment where higher test voltages are not required. The device offers PI and DAR measurements, a memory for 18 results, and a clear 9999-count display with a bar graph, which facilitates quick assessment of insulation condition without the need for additional software. Automatic discharge after measurement and high-voltage indication reduce the risk of working with a charged object. Additional messages for out-of-range and low battery help prevent erroneous readings.
