What is a Milometer? - Definition, Uses, and Accuracy

Milometer (or milliohm meter) is an instrument used to measure electrical resistance, specifically very low resistances. It is a type of ohmmeter that measures resistance in the range of milliohms (10^-3 ohms).

A milometer is typically used in applications where very precise measurements of resistance are required, such as in the testing of electronic components or in scientific research. The instrument works by applying a small voltage to the device being tested and measuring the resulting current flowing through it. The resistance of the device can then be calculated based on the voltage and current readings.

Milometers are available in different ranges, such as 10 milliohms, 1 milliohm, and 0.1 milliohm. They are typically more accurate than other types of ohmmeters and can measure resistances that are too low for other instruments to detect.
