Kyoritsu 3128

The Kyoritsu 3128 High Voltage Insulation Tester is a high-precision instrument designed for the most demanding insulation testing tasks. It offers six selectable test voltages — 500 V, 1000 V, 2500 V, 5000 V, 10000 V and 12000 V — allowing it to measure insulation resistance to very high ranges across an exceptionally broad set of applications. This flexibility makes it a powerful tool wherever high-voltage insulation must be verified with confidence.

The 3128 is ideally suited to high-voltage cables, large motors and generators, transformers, switchgear and substation equipment, where insulation faults can cause costly outages and serious safety risks. By applying appropriate test voltages, technicians can thoroughly assess insulation condition during commissioning, preventive maintenance and fault investigation, identifying weaknesses long before they develop into failures.

Built for accuracy and reliability, the Kyoritsu 3128 supports safe, compliant testing programs across utilities, mining, heavy industry and infrastructure. Hinco Instruments supplies the 3128 across Perth and Western Australia and provides full calibration and repair services to keep your instrument accurate and traceable.
