The Kyoritsu 3125A is a digital, high voltage insulation tester, capable of testing insulation resistance up to 5kV. The 3125A insulation tester is easy to operate featuring a large digital backlit display and also has the functionality to test both the polarization index (PI) and dielectric absorption (DA) ratio.
The Kyoritsu 3125A tests up to 1TΩ across 5 voltage ranges 250V, 500V, 1000V, 2500V and 5000V . An indication of the output voltage and discharge voltage is displayed on the screen. A filter function allows the Kyoritsu 3125A to obtain stable measurements by reducing noise interference in industrial environments.
The Kyoritsu 3125A also can to perform polarization index (PI) and the dielectric absorption ratio (DAR) testing. The 3125A has a live voltage warning for safety and auto power off to preserve battery consumption.
The Kyoritsu 3125A is supplied with a 3m line probe, 3m earth cord, 3m Guard cord, a Hook type prod, batteries and a Hard carry case.
