Resistance testers and ohmmeters play a vital role in electrical maintenance, troubleshooting, and compliance testing. By accurately measuring resistance across cables, windings, and connections, they help technicians identify weaknesses before they lead to failures, downtime, or safety hazards. Our lineup includes two primary categories:
These instruments apply high DC test voltages to measure very high resistance values, often in the megohm to teraohm range. As specialized ohmmeters, they are used to verify the integrity of insulation in cables, transformers, and motors, ensuring systems remain safe and dependable.
These testers use high test currents and four-wire measurement techniques to capture very low resistance values down to micro-ohms. Also referred to as low-resistance ohmmeters, they are essential for checking the quality of breaker contacts, busbar joints, welds, and grounding bonds where reliable, low-resistance connections are critical.
Together, these resistance testers and ohmmeters provide complete coverage for both high-resistance and low-resistance applications, making them indispensable tools for utilities, industrial plants, and field service technicians.
