MD5060B 5kV Smart Insulation Tester

The TENTECH MD5060B is a smart, 5 kV insulation tester and analyzer designed for both laboratory and field applications. It measures insulation resistance up to 5 TΩ and includes advanced features like automatic calculation of Polarization Index (PI) and Dielectric Absorption Ratio (DAR), step voltage tests, programmable pass/fail limits, and continuity testing.

With a built-in printer, memory for 4000 results, USB connectivity, and TLogger software, the MD5060B simplifies test reporting and predictive maintenance. The rugged, IP65-protected housing, rechargeable LFP battery, and high accuracy make it a reliable tool under harsh operating conditions.
