UNI-T UT505B Advanced Insulation Resistance DMM – 1000V, 200GΩ

The UNI-T UT505B is the flagship 1000V insulation multimeter in the 500 series. It vastly outperforms the UT505A by offering a staggering 200GΩ maximum resistance range. Furthermore, it incorporates Capacitance testing, Leakage Current measurement, Frequency testing, and an Auto Fuse Check. It is the ultimate forensic diagnostic tool for critical power infrastructure and high-end industrial maintenance.

Achieve absolute diagnostic supremacy with the UNI-T UT505B Advanced Insulation DMM. While the UT505A is an excellent tool, the UT505B is engineered for electrical forensics. When Pakistani engineers are troubleshooting critical infrastructure—such as power generation turbines or high-end pharmaceutical manufacturing lines—they need extreme sensitivity. The UT505B delivers this by expanding the resistance measurement limit to an astonishing 200GΩ.

This 2-in-1 True RMS Multimeter and 1000V Insulation Tester includes vital features missing from standard meters. It directly measures Leakage Current, allowing you to see exactly how much current is escaping through failing insulation. It also adds Capacitance and Frequency testing, essential for diagnosing complex motor start/run issues. The built-in Auto Fuse Check ensures your meter is always safe to operate, while the comprehensive PI/DAR and Step Voltage functions guarantee a perfect diagnostic profile every time.
