FMQJ57直流電阻電橋產(chǎn)品介紹（中文）
FMQJ57直流電阻電橋是一款采用凱爾文雙橋原理設(shè)計的精密測量儀器，適用于工礦企業(yè)、實驗室及現(xiàn)場環(huán)境下的低值直流電阻測量。該產(chǎn)品內(nèi)置電子檢流計與工作電源，無需額外附件即可完成高精度測量，操作便捷。其測量范圍覆蓋0.01μΩ至111.11MΩ，分辨力達(dá)0.01μΩ，滿足金屬導(dǎo)體電阻率、電機(jī)繞組電阻、開關(guān)接觸電阻等多樣化測量需求。電橋采用低溫度系數(shù)合金電阻元件，經(jīng)過嚴(yán)格工藝處理，確保測量穩(wěn)定性和準(zhǔn)確性。儀器配備機(jī)械與電氣雙重調(diào)零功能，支持靈敏度調(diào)節(jié)，并可通過外接電源或指零儀擴(kuò)展使用場景。環(huán)保設(shè)計支持交直流供電模式，減少電池更換頻率。外形尺寸為300×250×160mm，重量約6kg，便于攜帶。
FMQJ57特別適用于電線電纜、變壓器繞組等行業(yè)的電阻測量，其四端鈕接線法有效消除導(dǎo)線電阻干擾。內(nèi)置放大式指零儀提供清晰的平衡指示，而多檔倍率選擇（如×10⁻³至×10³）進(jìn)一步優(yōu)化測量精度。產(chǎn)品設(shè)計注重用戶體驗，如阻尼時間≤4秒、指針抗干擾設(shè)計等，適合復(fù)雜環(huán)境下的長時間連續(xù)工作。257
FMQJ57 DC Resistance Bridge (English)
The FMQJ57 DC Resistance Bridge is a precision instrument based on the Kelvin double bridge principle, designed for low-value DC resistance measurements in laboratories, industrial sites, and field environments. With a built-in electronic galvanometer and power supply, it enables standalone operation without additional accessories. Its measurement range spans 0.01μΩ to 111.11MΩ, achieving a resolution of 0.01μΩ, ideal for applications such as conductor resistivity testing, motor winding resistance, and switch contact resistance analysis.
Featuring alloy resistance components with low temperature coefficients and refined manufacturing processes, the FMQJ57 ensures consistent accuracy. The device includes mechanical and electrical zero-adjustment functions, adjustable sensitivity, and supports external power or galvanometer connections for extended use. Its eco-friendly design accommodates both AC/DC power modes, reducing battery dependency. Compact dimensions (300×250×160mm) and lightweight (6kg) enhance portability.
Tailored for industries like cable manufacturing and transformer production, the FMQJ57 employs a four-terminal connection method to minimize lead resistance interference. The amplified null detector provides clear balance indication, while multiple ratio settings (e.g., ×10⁻³ to ×10³) optimize precision. User-centric features include ≤4s damping time and anti-interference pointer design, suitable for prolonged operation in challenging conditions. 5928
