MD10KVR Digital Insulation Analyzer 10kV

About the MD10KVR:
The TENTECH MD10KVR is a high-performance digital insulation analyzer designed for advanced testing of insulation resistances up to 10 TΩ. With selectable test voltages from 500 V to 10 kV (25 V or 500 V increments), it incorporates advanced features such as step and ramp voltage testing, automatic PI/DAR calculation, leakage current and capacitance measurement, built-in printer, real-time clock, and 16,000-value memory with USB data transfer.

This rugged and portable unit is powered by a rechargeable LFP battery, offering reliable performance in both laboratory and field applications. Data can be transferred and analyzed using the included T-Logger software for automatic reporting and predictive maintenance.
