技術(shù)特點(diǎn)
本產(chǎn)品配備智能化檢流計系統(tǒng)，具有開機(jī)自檢功能，異常時會顯示故障提示。采用視窗平臺操作界面，支持全中文系統(tǒng)，設(shè)有實時反應(yīng)監(jiān)視畫面便于操作監(jiān)控。支持單/雙波長法、單/雙試劑法等多種檢驗方式，以及吸光度、終點(diǎn)法、動力學(xué)法等六種分析模式。獨(dú)特的樣本預(yù)稀釋功能和自動重測功能可智能處理超線性樣本，同時具備斷電保護(hù)能力，恢復(fù)供電后可繼續(xù)執(zhí)行原程序。儀器采用環(huán)保電池供電方案，配有專用清洗液和溫蒸餾水雙重清洗系統(tǒng)，確保測量穩(wěn)定性。110
應(yīng)用場景
UJ27C特別適合高校物理、化學(xué)實驗室的教學(xué)實驗，可直接測量1.5V干電池或2V蓄電池的電壓值。在工業(yè)領(lǐng)域，可用于校驗各類毫伏表、電子電位差計等儀表的刻度準(zhǔn)確性。配合標(biāo)準(zhǔn)電阻使用時，還能擴(kuò)展為直流電阻和電流的測量工具。其寬溫工作特性（5℃~35℃）和防腐蝕設(shè)計，使其在車間現(xiàn)場、野外作業(yè)等復(fù)雜環(huán)境中表現(xiàn)可靠。獨(dú)特的用戶管理密碼系統(tǒng)可分配不同操作權(quán)限，保障設(shè)備使用安全。132022
產(chǎn)品維護(hù)
儀器應(yīng)存放于相對濕度小于80%、無腐蝕性氣體的環(huán)境中。建議每年進(jìn)行一次校準(zhǔn)，長期不用時應(yīng)取出內(nèi)置電池。首次使用新電池需放電20-30分鐘以穩(wěn)定工作電流，若出現(xiàn)檢流計靈敏度下降情況，可更換6F22型9V疊層電池。各開關(guān)旋鈕定期旋轉(zhuǎn)可減少接觸氧化影響。設(shè)備提供完善的售后維護(hù)指導(dǎo)，用戶可通過簡單操作完成大部分日常維護(hù)工作。1028
Product Overview
The UJ27C DC Potentiometer is a portable high-precision instrument designed for measuring DC potential in laboratories, industrial sites, and educational settings. This self-contained unit features built-in transistor amplifier galvanometer, standard cell, and DC regulated power supply, eliminating the need for external accessories. With a measurement range of 0-2.110V and resolution down to 5μV, it achieves ±0.1% basic accuracy. The compact chassis (280×225×160mm) weighing 4kg ensures excellent portability for field applications. 2912
Key Features
This potentiometer incorporates intelligent galvanometer system with startup self-check function and fault prompts. The user-friendly interface supports Chinese display with real-time monitoring display. Multiple analysis modes are available including single/dual wavelength methods, endpoint method, kinetic method, etc. Unique features include sample pre-dilution function, automatic retest capability, and power failure protection that resumes previous operation. The environmentally friendly power system combines dedicated cleaning solution with warm distilled water rinse for measurement stability. 11326
Applications
Ideal for university physics/chemistry labs, it can directly measure 1.5V dry cells or 2V batteries. Industrial applications include calibration of millivolt meters and electronic potentiometers. When paired with standard resistors, it expands functionality for DC resistance and current measurement. The wide operating temperature range (5℃~35℃) and corrosion-resistant design ensure reliable performance in workshops and field environments. Multi-level password protection provides operational security. 202228
Maintenance
Store in environments below 80% humidity without corrosive gases. Annual calibration is recommended, with batteries removed during prolonged storage. New batteries require 20-30 minutes discharge for current stabilization. Replace 6F22 9V laminated battery if galvanometer sensitivity declines. Regular rotation of switches minimizes contact oxidation. Comprehensive after-sales guidance enables users to perform routine maintenance easily. 102728
