Martindale IN2203 Advanced Insulation Tester

The Martindale IN2203 Advanced Insulation Tester is a versatile instrument designed for both installation and service applications, offering a comprehensive range of measurement functions in one compact device. The unit combines a fully featured insulation tester with additional essential electrical test functions. It provides five selectable insulation test voltages up to 1000V, with measurement capability up to 20GΩ. A low-ohms earth-bond continuity test (200mA) is also included. For enhanced safety, the IN2203 features live circuit detection that prevents testing when voltage is present.

The IN2203 can accurately assess insulation quality and its stability over time by supporting measurement of both the Polarisation Index (PI) and the Dielectric Absorption Ratio (DAR). Additional functions include AC/DC voltage measurement up to 1000V, resistance measurement up to 600kΩ, and a continuity test with audible buzzer.

Built for durability, the IN2203 features a rugged design with a protective rubber holster for use in demanding environments. The large backlit LCD display ensures clear visibility in all lighting conditions, while auto power-off after 10 minutes helps extend battery life. The instrument comes complete with a Martindale TC57 heavy-duty nylon carry case for convenient storage of accessories, and a Martindale TL47 unfused test lead set is also included.
