Contact Resistance Meter

The Contact Resistance Meter(100M) Instrument provides precise measurements of electrical contact resistance using Kelvin’s 4-wire method, ensuring accurate results in the micro-ohm range. With a built-in 100A/200A DC current source, it simulates real-world conditions by measuring the millivolt drop across contact points. This makes it perfect for testing circuit breakers, isolators, disconnectors, and busbars in both high-voltage and low-voltage systems. Its portable design ensures easy transport and use in the field, making it ideal for testing in substations and power plants. By identifying resistance issues early, the meter helps prevent arcing, overheating, and costly system failures, ensuring the reliable operation of critical electrical infrastructure
