What is a Micro Ohmmeter?

A micro ohmmeter is a specialized instrument used to measure very low resistance values, typically in the micro-ohm range. It is commonly used in industries such as power generation, rail, automotive, and aerospace.

How Does a Micro Ohmmeter Work?

A micro ohmmeter works by applying a continuous current source to the material or conductor being tested and measuring the resulting voltage drop. The resistance value is then calculated using Ohm's Law (Resistance = Voltage/Current).

What are the Applications of a Micro Ohmmeter?

Micro ohmmeters are used for: Electrical cable testing Electric contact resistance testing Ground system effectiveness evaluation Weld quality inspection in metal structures and machinery
