Kyoritsu 3125A

The Kyoritsu 3125A High Voltage Insulation Tester is a robust instrument for verifying the integrity of insulation in high-voltage electrical equipment. With a wide range of test voltages from 250 V to 5000 V, it measures insulation resistance across a broad spectrum of applications, helping electricians and engineers detect deterioration, moisture ingress and insulation faults before they lead to failure or safety incidents.

Higher test voltages allow the 3125A to stress insulation more thoroughly than standard low-voltage testers, making it well suited to cables, motors, generators, switchgear and transformers where reliable insulation is critical. A clear, user-friendly interface and dependable performance make routine testing straightforward, whether for preventive maintenance, commissioning or fault diagnosis.

Trusted across industrial, mining, utility and commercial settings, the Kyoritsu 3125A supports safe, compliant electrical maintenance programs and helps extend equipment life by identifying problems early. Hinco Instruments supplies the 3125A throughout Perth and Western Australia and offers full calibration and repair services so your tester stays accurate and traceable.
