Hioki Resistance Meter RM3544

The Hioki RM3544 Resistance Meter is an essential tool in the realm of electrical engineering, renowned for its high-precision measurement capabilities across a wide spectrum of resistance values. This easy-to-use device is particularly suited for both manual and automated production lines, where it excels in measuring the winding resistance of motors and transformers as well as the contact resistance of power relays, switches, and connectors.

High Precision Across a Broad Range

The RM3544 stands out with its extensive measurement range, from a minimal 0.001 mΩ up to 3.5 MΩ. This range makes it ideal for a variety of applications, including testing solenoids, choke coils, transformers, and motors. Its versatility ensures that it can meet the diverse needs of industries relying on precise resistance measurements for quality control and assurance.

Temperature Compensation Function

One of the unique features of the RM3544 is its ability to measure both temperature and resistance simultaneously. Recognizing that the resistance of copper wires and other materials can vary with temperature changes, Hioki has equipped the RM3544 with a sophisticated temperature compensation function. This feature allows the meter to automatically adjust the resistance measurement to account for temperature effects, providing what is known as the true resistance. This functionality is critical in applications where precise resistance measurements are necessary to ensure the performance and safety of electrical components and systems.
