MD5KVR Digital Insulation Analyzer 5kV

About the MD5KVR:
The TENTECH MD5KVR is a state-of-the-art digital insulation analyzer designed to measure insulation resistances up to 5 TΩ. With selectable voltages from 50 V to 5 kV (steps of 25 V or 500 V), it combines advanced testing features with high accuracy and safety. It includes automated PI/DAR calculations, ramp and step voltage testing, dielectric discharge analysis, capacitance and leakage current measurement, plus a built-in printer and large internal memory.

Measured values are stored in non-volatile memory (up to 16,000 readings), printed directly, or transferred via USB to the included T-Logger software for further analysis and automatic report generation. Designed for both laboratory and harsh field environments, the MD5KVR offers reliable performance with rugged IP65 protection and rechargeable LFP battery operation.
