MD5060x 5kV Smart Insulation Tester

About the MD5060x:
The TENTECH MD5060x is a smart, microprocessor-controlled, 5 kV insulation tester designed for advanced insulation analysis. It measures insulation resistances up to 5 TΩ and can automatically calculate the polarization index (PI) and dielectric absorption index (DAR), simplifying transformer and high-voltage equipment testing.

Test voltages are selectable from 500 V to 5 kV in 100 V increments. The stabilized HV generator ensures high accuracy, while the built-in printer, memory for up to 4000 results, and USB interface with T-Logger software streamline reporting and predictive maintenance.

Rugged and portable with IP54 protection, rechargeable LFP battery, and a strong impact-resistant cabinet, the MD5060x is suitable for both laboratory and field conditions.
