FMQJ26直流雙臂電橋
FMQJ26直流雙臂電橋產品中文介紹
FMQJ26直流雙臂電橋是一款采用惠斯登電橋電路設計的便攜式精密測量儀器，主要用于中等阻值電阻（1Ω～9.999MΩ）的準確測量。其電路設計優(yōu)化了傳統(tǒng)電橋的性能，適合實驗室、車間及戶外環(huán)境使用。產品分為市電型和電池型兩種供電模式，其中型號前綴“FM”代表市電型，可直接接入220V交流電源，適合固定場所；無前綴則為電池型，便于現(xiàn)場或無電源環(huán)境下操作。儀器內置高靈敏度電子檢流計，無需外接附件即可快速完成電阻測量，測量步進精度可達5μΩ，滿足金屬導體電阻率、電機繞組電阻等低阻值場景的檢測需求。機身采用緊湊設計（260×215×140mm），重量輕便，兼顧耐用性與操作便捷性。通過四端連接法可有效減少接線電阻和接觸電阻的影響，提升小電阻測量的準確性。121317
FMQJ26 DC Double Bridge Product Introduction in English
The FMQJ26 DC double bridge is a portable precision instrument based on the Wheatstone bridge circuit, designed for accurate measurement of medium-range resistance (1Ω to 9.999MΩ). It features two power modes: AC-powered (marked with "FM" prefix) for stable lab use and battery-powered for field applications. The built-in high-sensitivity electronic galvanometer eliminates the need for external accessories, enabling rapid resistance measurement with a resolution of 5μΩ. Its compact design (260×215×140mm) ensures portability, while the four-terminal connection method minimizes the impact of lead resistance and contact resistance, enhancing accuracy in low-resistance measurements such as metal resistivity or motor winding tests. The instrument is suitable for diverse environments, including industrial sites and research facilities, offering reliable performance without complex setup.11829
產品特點與適用場景
FMQJ26直流雙臂電橋在功能設計上注重實用性與適應性。其寬量程覆蓋中阻到低阻測量需求，尤其適合電機、變壓器繞組電阻、開關接觸電阻等工業(yè)檢測場景。市電型版本采用環(huán)保設計，無需頻繁更換電池；電池型版本則通過優(yōu)化電路降低功耗，延長戶外使用時長。操作界面直觀，配備步進盤和滑線盤雙調節(jié)系統(tǒng)，用戶可根據(jù)被測電阻預估值快速選擇倍率（如×0.01、×1等），結合靈敏度可調的檢流計實現(xiàn)精準平衡。儀器適用于材料研究、設備維護及教育實驗等領域，幫助用戶高效獲取可靠數(shù)據(jù)。2722
Key Features and Applications
The FMQJ26 excels in versatility with its wide measurement range, catering to both industrial and educational needs. The AC-powered version provides continuous operation, while the battery-powered model ensures mobility. Its dual adjustment system (step dial and slide wire) simplifies operation, allowing users to select appropriate multipliers (e.g., ×0.01, ×1) based on estimated resistance values. The adjustable galvanometer sensitivity further enhances measurement precision. Typical applications include quality control of electrical components, material conductivity analysis, and academic experiments, offering a balance between performance and ease of use.71721
