The Motwane Manufacturing Company Private Limited

The MCRM Conductor Resistance Meter is a high‑precision micro‑ohmmeter designed to accurately measure very low resistance values of conductors. It is suitable for measuring DC resistance of copper, aluminium, alloy, and coated conductors using a true 4‑wire measurement technique. The instrument delivers high measurement current up to 10A, enabling fast and accurate readings even for low resistance values starting from 0.1 µΩ. It features a 4.3-inch color TFT display, inbuilt thermal printer, and Bluetooth & USB connectivity for seamless data handling and reporting. With advanced features like temperature correction, length correction, and protection against back EMF, the MCRM ensures reliable performance in both production environments and field-testing applications.
