Description

Amprobe AMB 50

The Amprobe AMB-50 High-Voltage Insulation Tester is equipped with essential features for professional insulation diagnostics. It includes the ability to calculate PI (Polarization Index) and DAR (Dielectric Absorption Ratio) parameters. Additionally, the PASS/FAIL comparison function enhances testing efficiency and productivity.

The readings are shown clearly on a large, backlit LCD display. The instrument also includes Windows-compatible PC software and a USB communication port, allowing for easy connection to a PC and efficient management of recorded test data.
