FNIRSI MRT-1050 Insulation Resistance Tester

The FNIRSI MRT-1050 is a professional digital megohmmeter engineered for measuring the insulation resistance of electrical equipment, cables, motors, and transformers. It provides a reliable solution for assessing the integrity of electrical systems in industrial and residential environments.

Key Features
- Offers four selectable test voltage ranges (100V, 250V, 500V, and 1000V) with resistance measurements up to 20 GΩ.
- Performs integrated AC/DC voltage measurements for enhanced diagnostic utility.
- Supports advanced insulation health assessments through Polarization Index (PI) and Dielectric Absorption Ratio (DAR) calculations.
- Ensures user safety with an automatic discharge function that clears residual voltage after testing.
- Features a rugged construction with protective silicone bumpers and a large backlit LCD for visibility in low-light conditions.

Applications
With its wide voltage range and diagnostic capabilities, this device is ideal for routine maintenance and troubleshooting of motors, power cables, and transformer insulation.
