英文介绍
The SDAR SMT-1B compact analog multimeter embodies Shanghai SDAR Electronic Instruments decades of expertise in precision meter manufacturing. This pocket-sized tool measures 100×69×32mm and weighs approximately 116g, featuring a durable rubber-coated casing that provides both shock resistance and comfortable grip. Its crisp white dial with red pointer offers excellent visibility, complemented by a smooth-rotating selector knob with positive detent positions.28
Core functions include DC/AC voltage measurement (10/50/250/500V ranges), DC current testing, resistance checking with audible continuity buzzer, and basic dB level detection (-20dB to +56dB). The meter movement utilizes a sensitive 20KΩ/V magnetoelectric system with mirror-backed scale to minimize parallax errors. Alligator clip-ready test leads store conveniently in the included carrying case alongside multilingual instructions.1728
Ideal for fieldwork and educational applications, this analog multimeter maintains SDAR s tradition of reliable performance through optimized internal magnetic circuit design and precision-balanced movement components. The scratch-resistant lens, battery-saving auto-off feature (powered by standard AA battery), and color-coded jacks demonstrate thoughtful engineering tailored for daily troubleshooting tasks.914
