QJ60 Teaching Single-Double Arm Bridge Product Introduction (English)
The QJ60 Teaching Single-Double Arm Bridge is a precision resistance measuring instrument designed for educational experiments, integrating both Wheatstone (single-arm) and Kelvin (double-arm) bridge circuits. It features a broad measurement range from 10⁻⁴Ω to 11.11Ω in double-arm mode for low-resistance measurements, and 1Ω to 111.1kΩ in single-arm mode for medium-high resistance tasks, covering experiments such as metal resistivity and motor winding resistance tests. The environmentally conscious design allows direct connection to mains power, with built-in galvanometer and adjustable power supply for standalone operation without additional accessories. The intuitive panel includes sensitivity adjustment knobs, ratio switches, and four-terminal binding posts to facilitate student comprehension of bridge balance principles. The impact-resistant housing (290×220×130mm) suits both laboratory and field teaching scenarios. Its linkage adjustment mechanism minimizes lead resistance interference, delivering stable results for effective hands-on learning of precision measurement techniques. 41524
技術(shù)特點(diǎn)補(bǔ)充說(shuō)明
該產(chǎn)品通過(guò)優(yōu)化電路設(shè)計(jì)降低了接觸電阻對(duì)測(cè)量精度的影響，雙臂模式下采用四端接法可有效消除引線誤差。儀器提供多檔位倍率選擇，最小分辨力達(dá)5μΩ（雙臂）和1mΩ（單臂），適合演示不同量級(jí)電阻的測(cè)量方法對(duì)比。工作電源支持1.5V-24V寬電壓輸入，適配各類(lèi)教學(xué)場(chǎng)景需求。檢流計(jì)具備機(jī)械鎖扣和電子調(diào)零功能，保護(hù)器件的同時(shí)提升操作便捷性。2716
Educational Value Highlights
This equipment demonstrates fundamental concepts of comparative measurement through visual bridge balancing process. The clear terminal markings (C1/P1/C2/P2) help students master four-wire resistance measurement methodology. Dual-mode switching enables comparative studies between single-arm and double-arm configurations, deepening understanding of error sources in precision instrumentation. The modular design allows optional connection of external standard resistors for advanced experimental extensions. 182528
