Low-resistance ohmmeters are essential for verifying the integrity of electrical bonds, breaker contacts, busbar joints, welds, and grounding connections. By applying high test currents (often 10 A, 100 A, or more) with four-wire Kelvin measurement, these DLRO testers provide precise readings down to micro-ohms, helping technicians identify potential weaknesses before they lead to overheating or failure.

Megger Low-Resistance Testers

Megger pioneered the DLRO concept and remains a benchmark in the industry. Their instruments combine portability, high-current capability, and advanced safety features to ensure dependable results across field and laboratory environments.

AEMC Low-Resistance Testers

AEMC's models deliver high-accuracy low-ohm measurements with rugged construction for tough field conditions. Many units include multiple test current ranges, data logging, and connectivity options for streamlined analysis and reporting.
