Hioki RM3544 Resistance Meter
The Hioki RM3544 is a high-precision DC resistance meter designed for measuring low resistance values with exceptional accuracy. It offers a wide measurement range from 0.000 mΩ to 3.5 MΩ and features a maximum resolution of 1 μΩ. This instrument is ideal for applications such as testing the winding resistance of motors and transformers, as well as the contact resistance of power relays, switches, and connectors.
Description
The Hioki RM3544 is designed to deliver highly accurate and dependable resistance measurements over a wide range. By employing a four-terminal measurement method, it effectively minimizes the influence of lead and contact resistance, ensuring precise results even for very low-resistance components.
This meter features a broad measurement range from 0.000 mΩ to 3.5 MΩ, with a resolution down to 1 μΩ, making it ideal for detailed testing of resistive elements. It provides a high basic accuracy of 0.02% and includes temperature compensation with ±0.5°C accuracy to account for variations caused by environmental changes.
The RM3544 offers multiple measurement speeds—fast (21 ms), medium (101 ms), and slow (401 ms)—allowing users to balance speed and stability based on the testing scenario. Its intuitive interface and clear display simplify operation, while built-in data storage enables convenient recording and review of measurement results. Additionally, RS-232C and USB connectivity provide seamless data transfer and remote control capabilities.
Versatile and reliable, the RM3544 is suitable for both manual measurements and integration into automated production systems, making it a valuable tool for testing motors, transformers, switches, relays, and other low-resistance components.
