Mextech DIT54 Digital Insulation Tester

Mextech DIT54 Digital Insulation Tester

The Mextech DIT54 Digital Insulation Tester is a professional high-voltage insulation resistance tester designed for electricians, industrial maintenance engineers, power utilities, telecom industries, and electrical testing professionals. This advanced insulation tester delivers accurate insulation diagnostics for transformers, motors, generators, high-voltage cables, switchgear, arresters, and large industrial electrical systems.

Built with multiple selectable test voltages including 250V, 500V, 1000V, 2500V, 5000V, and 10kV, the DIT54 supports insulation resistance measurement from 0.5MΩ up to 5TΩ with high precision and stable performance. The tester features advanced IR (Insulation Resistance), PI (Polarization Index), and DAR (Dielectric Absorption Ratio) testing functions, making it ideal for preventive maintenance and insulation condition analysis in demanding industrial environments.
