QJ83A Digital DC Wheatstone Bridge Product Introduction (English)
The QJ83A Digital DC Wheatstone Bridge is an intelligent measurement instrument designed for precise resistance testing, suitable for laboratory, industrial field, and electronic component manufacturing applications. Featuring digital measurement technology, this device covers a wide measurement range from 0.1μΩ to 11.000MΩ with basic accuracy of ±0.05%, meeting various DC resistance measurement requirements.
Equipped with a high-sensitivity four-terminal measurement interface, the instrument effectively eliminates the influence of contact resistance and lead resistance. The clear four-and-half-digit LCD display provides direct reading capability, working in tandem with automatic range switching technology to quickly identify optimal measurement ranges. Multiple anti-interference designs ensure stable performance in complex electromagnetic environments, with temperature drift coefficient maintained below 5ppm/℃.
The user-friendly interface incorporates ergonomic controls including anti-slip knobs and wear-resistant buttons. Practical functions such as data hold and relative value measurement enhance operational efficiency. With measurement response time under 0.8 seconds, the device achieves over 300 continuous measurements per hour. The built-in rechargeable lithium battery provides up to 12 hours of operation, complemented by DC power input for flexible power supply options.
Constructed with industrial-grade ABS housing and shock-absorbing protection structure, the compact device weighs less than 1.2kg. It is particularly suitable for quality inspection of transformer windings, motor coils, and precision resistors, while also serving educational and research purposes. Through optimized circuit design and component selection, the instrument demonstrates excellent long-term stability with annual drift typically controlled within 0.02% of full scale under normal operating conditions.
