UNI-T UT53 Digital Multimeter with Insulation Tester

The UNI-T UT53 is a professional digital multimeter and insulation tester that delivers precise measurements up to 1000V DC and 1000V AC True RMS. Its standout capability is insulation resistance testing up to 10GΩ with selectable test voltages from 50V to 1000V, making it ideal for diagnosing motor windings, cables, and electrical installations.

Advantages

This instrument combines a 6000-count multimeter with a full-featured insulation tester. Auto-ranging simplifies operation, while True RMS ensures accurate readings on non-sinusoidal waveforms. The large backlit display and data hold function improve usability in dim environments. Safety is paramount: CAT III 1000V and CAT IV 600V ratings allow confident use in industrial and utility settings.
