UNI-T UT503PV Insulation Resistance Tester

Product detailed description

We offer a 3-year warranty on this product.

UT503PV digital insulation resistance tester can be used to measure insulation resistance with photovoltaic power supply (maximum: 1000V DC) and conventional insulation resistance (without power supply) and automatic AC/DC voltage identification. It has several functions, including: photovoltaic insulation resistance measurement without solar panel during power failure/short circuit or at night, voltage grading, Bluetooth transmission, automatic discharge, high voltage warning, remote-controlled test lead operation others. UT503PV is commonly used to test insulation resistance for various equipment such as photovoltaic panel, battery energy storage system, etc.
