Insulation Resistance Tester

The ATB AT6850 is a high-performance professional tester built for industrial automation insulation testing, balancing precision, efficiency and operational safety — from batch component QC to complete-equipment insulation testing, a reliable choice for electrical manufacturing and power O&M. Its industry-leading three-channel independent design assigns pre-charge, hold and test to separate channels running synchronously without interference, eliminating repeated rewiring and raising throughput more than 60% over traditional single-channel units — a perfect match for automated production-line batch testing.

Ample power reserves support 1000 V output voltage and 2 A output current with 2000 W rated power, keeping measurements stable and accurate even with large capacitive devices under test and continuous operation, avoiding measurement deviation caused by insufficient power.
