技術(shù)特性
儀器提供三檔倍率選擇（×0.1/×1/×10），覆蓋10μV~2.110V的寬量程，最小分辨力達(dá)1μV，基本誤差限為±0.05%讀數(shù)+0.5μV。工作電源采用4節(jié)1號(hào)干電池與2節(jié)6F22疊層電池組合供電，具有環(huán)保便攜特性。機(jī)身采用耐沖擊結(jié)構(gòu)設(shè)計(jì)，尺寸為310×240×160mm，重量約5kg，符合野外作業(yè)需求。內(nèi)置檢流計(jì)靈敏度可達(dá)1×10⁻⁸A/mm，并具備50Hz/500V耐壓能力，確保工業(yè)環(huán)境下的穩(wěn)定工作。51117
應(yīng)用場(chǎng)景
該設(shè)備特別適用于熱電偶標(biāo)定、電極電位分析、霍爾效應(yīng)磁場(chǎng)測(cè)量等科研實(shí)驗(yàn)，同時(shí)能對(duì)毫伏表、電子電位差計(jì)等工業(yè)儀表進(jìn)行快速校驗(yàn)。在高校物理化學(xué)實(shí)驗(yàn)中，其×10檔位（0-2.110V）可直接用于電源內(nèi)阻測(cè)定和酸堿度檢測(cè)，操作時(shí)通過(guò)補(bǔ)償法原理實(shí)現(xiàn)無(wú)損耗測(cè)量，避免傳統(tǒng)電壓表分流誤差。62122
Product Overview
The UJ33b DC (High) Potentiometer is a precision portable measuring instrument designed for laboratory, industrial field, and academic applications. Operating on the null-balance compensation principle, it directly measures DC EMF and thermocouple signals, with expandable capabilities for current and resistance measurements when paired with standard resistors. Its integrated transistorized null detector and unsaturated standard cell ensure minimal temperature drift and outstanding stability, maintaining reliability within 0-35℃ operating conditions. 1410
Key Features
With three range multipliers (×0.1/×1/×10), the device covers 10μV~2.110V measurement span at 1μV resolution, featuring ±0.05%rdg+0.5μV basic accuracy. The dual-power system combines 4×R20 and 2×6F22 batteries for field operation. Its 310×240×160mm rugged chassis (5kg weight) incorporates a high-sensitivity galvanometer (1×10⁻⁸A/mm) and withstands 500V/50Hz insulation tests, suitable for harsh industrial environments. 51215
Typical Applications
Ideal for thermocouple calibration, electrode potential analysis, and Hall-effect experiments in research labs, it also serves as a portable calibrator for millivolt meters and industrial potentiometers. In university settings, the ×10 range enables direct battery internal resistance measurements and pH value detection through its non-loading measurement methodology, eliminating shunt errors caused by conventional voltmeters. 61920
