Micro-Ohmmeters

Micro-ohmmeters fall within the family of low-resistance ohmmeters, but they specialize in the very lowest resistance measurements — down to micro-ohms. While general low-resistance testers cover a wider range, micro-ohmmeters provide the resolution and high-current injection needed to test critical connections like breaker contacts, busbars, and welded joints.

AEMC Micro-Ohmmeters

AEMC designs micro-ohmmeters that balance accuracy, ruggedness, and ease of use. Many models provide multiple test current ranges, data logging, and connectivity options for streamlined reporting. Their durable construction makes them well-suited for demanding environments where precision and reliability are critical.

Megger Micro-Ohmmeters

Megger's micro-ohmmeters are industry benchmarks, offering high test currents, four-wire Kelvin accuracy, and robust safety features. Their portable DLRO units and higher-current systems are used worldwide to verify the quality of electrical connections in both field and laboratory settings. These instruments ensure reliable performance when even the smallest resistance values matter.

Whether commisioning new equipment or performing preventative maintenance, micro-ohmmeters from Megger and AEMC deliver the high-accuracy testing required to ensure safe, low-resistance connections.
