T-RM5000 Insulation Resistance Tester

The T-RM 5000 Insulation Resistance Tester performs local insulation tests to confirm the with-stand level and determine the absorption ratio and polarization index of capacitive samples. Typical applications include cables, transformers, motors / generators, circuit breakers and bushings. The -unit has a compact structure, easy operation, built-in rechargeable battery, and can also be equipped with ordinary batteries. T-RM 5000 type resistance measurement can reach up to 50GΩ.

The instrument has a clear liquid crystal display, showing the insulation resistance reading as a digital display function. The conventional voltage setting is available in 500V, 1000V, 2500V, 5000V steps and can be fine-tuned in with adjustment steps of 50V.
