FMQJ44a DC Double Bridge Product Introduction
The FMQJ44a DC double bridge is a laboratory-grade measuring instrument designed for precise resistance detection. Based on the classical double bridge principle, this device achieves high-stability measurement of low-value resistors through optimized circuit design and key component selection. Its enhanced anti-interference capability makes it suitable for industrial testing, scientific research, and educational applications.
Technical features include an intelligent temperature compensation module that automatically adjusts measurement parameters according to ambient conditions, ensuring consistent results across varying environments. The scientifically designed measurement range covers micro-ohm to medium-value resistance detection. The layered internal structure effectively minimizes contact resistance interference. The user interface combines a digital display with rotary controls for rapid parameter setting and real-time data reading. Multiple protection mechanisms support prolonged operation, including automatic overload cutoff and error alerts.
Application scenarios encompass conductive material analysis, electronic component inspection, electrical equipment contact resistance testing, and new energy battery module evaluation. The compact and lightweight design enhances portability for field operations, with compatibility for various external probes to expand measurement possibilities.
Operational convenience is reflected in the modular terminal design allowing single-handed cable connection. The built-in rechargeable lithium battery provides up to 20 hours of continuous use. USB data export function works with mainstream analysis software for test record management. The system supports bilingual interface switching between Chinese and English to accommodate different user preferences.
