UNI-T Insulation Resistance Tester UT516B AC/DC Voltage Comparative Measurement Polarization Index UT-516B

The UT516B is a digital high voltage insulation resistance tester with 6 ranges: 500V, 1000V, 2500V, 5000V, 10000V and 12000V. Fine adjustment of voltage with 10% step at each range (except 12000V) is available. Test data can be saved in the tester memory and transferred to a PC via the dedicated USB cable, or be transferred to a PC in real time. The tester, with high performance and easy operation, is widely used in the measurement and maintenance of power equipment and power
supply circuits.
