QJ47 DC Single/Double Bridge Product Introduction
The QJ47 DC Single/Double Bridge is a high-precision resistance measuring instrument designed for laboratories, research institutions, and industrial applications. Based on the classical bridge balance principle, this device supports both single-arm and double-arm bridge configurations through flexible wiring modes, accommodating resistance measurement tasks with varying accuracy requirements.
Equipped with a stable DC power supply and sensitive galvanometer system, the instrument covers a wide measurement range from 1μΩ to 11.11MΩ. Its optimized circuit design effectively minimizes interference from contact resistance and lead resistance, ensuring measurement accuracy. The intuitive rotary control panel enables operators to quickly complete range switching and balance calibration, significantly improving operational efficiency.
Featuring an all-metal protective casing and shock-absorbing structure, the QJ47 maintains reliable performance in challenging environments. The ergonomic panel layout with wear-resistant markings ensures clear functional zoning and ease of maintenance. The four-terminal connection mode effectively eliminates lead errors, making it particularly suitable for precision low-resistance measurements.
Typical applications include power system grounding resistance detection, motor winding analysis, and material conductivity testing. Compatible with both laboratory and industrial environments, its modular design facilitates maintenance and upgrades. Professional technical support services are available to help users customize measurement solutions and maximize equipment potential.
