Insulation Resistance Testers

Insulation resistance testers are critical tools used to evaluate the integrity of electrical insulation in marine, industrial, and commercial systems. These testers apply a high voltage to electrical equipment and measure the resistance of the insulation, helping to identify deteriorated wiring, moisture ingress, and other faults that could lead to short circuits or equipment failure.

Marine-grade insulation resistance testers are designed to withstand tough environmental conditions such as humidity, vibration, and salt air. They provide accurate readings across a wide range of voltages—typically from 250V to 1000V or higher—and are used on motors, generators, switchboards, power cables, and control systems.

These instruments may feature digital or analog displays, data hold functions, and automatic discharge of test voltage. Portable and easy to use, they are essential for preventive maintenance and safety checks on vessels and offshore platforms.
