產(chǎn)品概述
上海四達(dá)電子儀表有限公司生產(chǎn)的SMT-1B袖珍式指針萬用表是一款采用經(jīng)典磁電技術(shù)的便攜式測量儀表。該產(chǎn)品延續(xù)了品牌三十余年專業(yè)制造經(jīng)驗，以精巧外觀和穩(wěn)定性能著稱，特別適合電子維修、教學(xué)實驗及日常電路檢測等場景使用。表體采用人性化包膠設(shè)計，兼具防滑抗震特性，整體尺寸僅100mm×69mm×32mm，重量約116克，可輕松放入工具包隨身攜帶。28
功能特點
SMT-1B具備直流電壓、交流電壓、直流電流、電阻測量等基礎(chǔ)功能，其中直流電壓量程覆蓋10V/50V/250V/500V四檔，交流電壓測量范圍相同，精度控制在±4%-±5%之間。產(chǎn)品采用高靈敏度磁電式表頭，配備20KΩ/V的電壓靈敏度，確保測量數(shù)據(jù)清晰準(zhǔn)確。特別設(shè)計的蜂鳴導(dǎo)通測試功能可快速判斷線路通斷，而分貝測量檔位（-20dB～+56dB）滿足基礎(chǔ)音頻檢測需求。雙層刻度盤設(shè)計配合紅色指針，使讀數(shù)更加直觀便捷。2817
設(shè)計細(xì)節(jié)
該萬用表采用紅黑雙色包膠外殼，主體為耐沖擊ABS材質(zhì)，關(guān)鍵部位增加防護(hù)橡膠，既提升抗跌落性能又增強(qiáng)握持舒適度。隨附專用表筆符合人體工學(xué)設(shè)計，插接部位采用防誤插結(jié)構(gòu)。功能旋鈕經(jīng)過十萬次旋轉(zhuǎn)測試，檔位清晰明確且阻尼適中。內(nèi)置1.5V AA電池供電，配備低電量提示功能，電池倉采用螺絲固定確保使用安全。產(chǎn)品標(biāo)配含中英文雙語說明書、測試表筆及專用收納盒。1428
技術(shù)傳承
作為國內(nèi)較早引進(jìn)美國內(nèi)磁式儀表技術(shù)的企業(yè)，上海四達(dá)將三十余年積累的指針儀表制造經(jīng)驗融入SMT-1B產(chǎn)品。該型號延續(xù)了品牌經(jīng)典的SP系列設(shè)計語言，優(yōu)化了內(nèi)部磁路結(jié)構(gòu)和分流器布局，使指針偏轉(zhuǎn)更平穩(wěn)線性。生產(chǎn)過程中嚴(yán)格執(zhí)行工序檢驗，關(guān)鍵部件采用精密切削工藝，確保每塊儀表的一致性。產(chǎn)品適用于電子愛好者、職業(yè)教育及家庭基礎(chǔ)電路維護(hù)等用途。922
英文介紹
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
