Product Description
CM-101 Digital Micro-Ohm Meter is an advanced low-resistance testing instrument engineered for industries requiring ultra-precise measurements. Designed for cable manufacturers, electrical testing labs, panel builders, transformer workshops, and component testing, the CM-101 combines high accuracy with intelligent automatic calculations.
With a measurement range from 1 µΩ to 2 kΩ and accuracy within ±0.2% of reading, ±0.05% of range, the CM-101 ensures stable, reliable, and repeatable results. The 4-terminal Kelvin method eliminates lead resistance errors, making it ideal for extremely low-resistance measurements.
Unlike standard micro-ohm meters, the CM-101 offers advanced computational features, such as automatic conductivity, resistivity, diameter-based resistance calculation, and material-dependent results. Users can input the diameter and length of a conductor, and the instrument instantly displays:
-
RT (Actual Resistance)
-
Resistivity
-
Conductivity
-
Material-based parameters (e.g., Copper, Aluminium, etc.)
The inbuilt temperature sensor automatically corrects resistance to 20°C (R20), eliminating manual charts and ensuring higher accuracy.
