Martindale IN2203 Advanced Insulation Tester
The Martindale IN2203 Advanced Insulation Tester offers precise, reliable measurement for both installation and service applications. Designed for professional use, it combines a variety of essential testing functions into one compact and robust unit. Its clear LCD backlit display ensures easy readability, even in dimly lit environments, while the rubber holster protects the tester in harsh working conditions.
Versatile Electrical Testing
The Martindale IN2203 features five selectable insulation test voltages up to 1000V and can measure insulation resistance up to 20G Ohms. It provides low ohms earth-bond continuity testing at 200mA, ensuring accurate verification of circuit integrity. Additionally, users can measure both the Polarisation Index (PI) and the Dielectric Absorption Ratio (DAR), delivering key insights into insulation quality and performance over time.
Built for Accuracy and Safety
Standard functions include AC and DC voltage measurement up to 1000V, and resistance testing up to 600K Ohms. The continuity test includes an audible buzzer for quick feedback. With live circuit detection, the Martindale IN2203 ensures safety by identifying voltage presence before insulation tests begin. Auto power-off after ten minutes extends battery life, making it both efficient and reliable on site.
Practicality is central to the Martindale IN2203. It comes supplied with a durable TC57 carry case, TL47 unfused test leads, and a clear user manual. Its ergonomic design and robust construction make it ideal for long-term use across a range of installation and maintenance environments.
