Martindale Electric introduces IN2203 insulation tester

Martindale Electric, a manufacturer of electrical test equipment, has launched the IN2203 Advanced Insulation Tester, a compact, multifunction instrument designed for both installation and service applications.

The device combines a range of electrical test functions, enabling users to measure insulation quality and perform additional diagnostic checks using a single unit.

With five selectable test voltages ranging from 50V to 1000V, the IN2203 can measure insulation resistance up to 20GΩ.

It also features a low-ohms earth-bond continuity test (200 mA) and an automatic live circuit detection function that prevents insulation testing on energised circuits, ensuring user safety.

Designed for field use

To support long-term monitoring of insulation performance, the tester includes measurement functions for both Polarisation Index (PI) and Dielectric Absorption Ratio (DAR), providing engineers with indicators of insulation condition over time.

The IN2203 also measures AC and DC voltage up to 1000V, resistance up to 600kΩ, and includes a continuity test with an audible buzzer. These features make it suitable for troubleshooting and maintenance tasks across a variety of electrical systems.

Designed for reliability in demanding environments, the instrument comes with a rubber holster for impact protection and a large, backlit LCD display for use in low-light conditions.

An automatic power-off function after ten minutes helps preserve battery life and the unit meets safety standards EN 61010 600V CAT IV and 1000V CAT III.

Supplied accessories include the Martindale TC57 heavy-duty nylon carry case, a TL47 unfused test lead set, and a user manual.
