Product Overview
The FMQJ24 DC Resistance Bridge is a portable high-precision instrument designed for measuring low-value DC resistance in industrial, laboratory, and field environments. Featuring an eco-friendly design, it operates directly via mains power without batteries, eliminating chemical waste concerns. Utilizing a Kelvin double-bridge circuit, the device effectively minimizes lead resistance interference to ensure measurement accuracy. Integrated with a high-sensitivity electronic galvanometer and stabilized power supply, it offers user-friendly operation and reliable performance for applications such as metal resistivity testing, motor winding resistance analysis, and contact resistance measurement. 39
Technical Features
With a measuring range of 0.1mΩ to 110mΩ and basic accuracy of 0.05%, the FMQJ24 provides a resolution of 5μΩ. Its four-terminal connection method and auto-ranging function adapt seamlessly to diverse resistance values. The compact chassis (310×255×160mm) weighs approximately 3kg, ensuring portability. The intuitive panel includes sensitivity adjustment knobs and multiplier switches for effortless zeroing and measurement. Enhanced anti-interference capability and low temperature drift enable stable performance within 5℃~45℃ operating conditions. 2414
Applications
This product is widely used in power systems, telecommunications, and manufacturing sectors, particularly for cable fault diagnosis (e.g., breaks or shorts), transformer winding tests, and switch contact resistance analysis. Its precision also supports material conductivity research in scientific institutions. When paired with auxiliary fixtures, it extends to metal sample resistivity testing. The design prioritizes both functionality and safety for on-site operations. 613
