PHS-25數(shù)顯酸度計(jì)/PHS25
產(chǎn)品概述
PHS-25數(shù)顯酸度計(jì)是一款高精度實(shí)驗(yàn)室測量儀器，采用31/2位液晶數(shù)字顯示技術(shù)，可同時(shí)顯示pH值和溫度值。該儀器廣泛應(yīng)用于化工、制藥、食品加工、環(huán)保等領(lǐng)域的水溶液酸堿度檢測，具備pH和mV雙重測量功能。儀器采用手動(dòng)溫度補(bǔ)償設(shè)計(jì)，測量范圍覆蓋0.00-14.00pH，最小顯示單位為0.01pH，滿足常規(guī)實(shí)驗(yàn)室精密測量的需求。11215
The PHS-25 digital pH meter is a high-precision laboratory instrument featuring a 3.5-digit LCD display that simultaneously shows pH and temperature values. Designed for aqueous solution testing in chemical, pharmaceutical, food processing and environmental fields, it offers dual measurement capabilities for both pH and mV. With manual temperature compensation and a measuring range of 0.00-14.00pH (resolution 0.01pH), this device meets routine laboratory accuracy requirements.
核心特點(diǎn)
該產(chǎn)品采用藍(lán)色背光雙排液晶顯示，讀數(shù)清晰直觀，配備E-201-C型復(fù)合電極反應(yīng)快速穩(wěn)定。儀器具有二點(diǎn)校準(zhǔn)功能，支持斜率補(bǔ)償，輸入阻抗高達(dá)3×10¹¹Ω，能有效減少測量誤差。整機(jī)設(shè)計(jì)輕巧緊湊（220×160×65mm），重量僅1kg，操作界面簡潔，適合不同場景下的移動(dòng)使用。特殊的電極支架設(shè)計(jì)便于固定傳感器位置，確保測量穩(wěn)定性。51822
Key features include blue backlit dual-row LCD display for clear readings, paired with responsive E-201-C composite electrode. The two-point calibration with slope compensation and high input impedance (3×10¹¹Ω) minimizes measurement deviations. Its compact design (220×160×65mm, 1kg) with intuitive interface allows flexible deployment, while specialized electrode holder ensures stabilization during operation.
應(yīng)用場景
適用于科研機(jī)構(gòu)、水質(zhì)監(jiān)測站、高校實(shí)驗(yàn)室等場所，可精確檢測飲用水、廢水、培養(yǎng)基等液體的酸堿度。在農(nóng)業(yè)領(lǐng)域可用于土壤分析，食品行業(yè)能監(jiān)控發(fā)酵過程，環(huán)保部門則應(yīng)用于污水處理監(jiān)測。儀器配套的電位測量功能還可用于簡單的氧化還原電位檢測，擴(kuò)展了使用場景。131925
Ideal for research institutions, water quality stations and academic labs to analyze liquids like drinking water, wastewater and culture media. Agricultural soil testing, food fermentation monitoring and environmental wastewater treatment are typical applications. The included mV measurement extends functionality to basic ORP detection scenarios.
操作說明
儀器采用標(biāo)準(zhǔn)化操作流程：開機(jī)預(yù)熱后，先用pH6.86緩沖液定位，再用pH4.0/9.18緩沖液進(jìn)行斜率校準(zhǔn)。日常使用中建議每周校準(zhǔn)一次，電極需保存在3mol/L氯化鉀溶液中以延長使用壽命。測量時(shí)只需將處理后的電極浸入樣品，輕輕攪拌后讀取穩(wěn)定數(shù)值即可。212327
Standard operation involves warm-up, calibration with pH6.86 buffer first then pH4.0/9.18 buffer for slope adjustment. Weekly calibration is recommended, with electrode storage in 3mol/L KCl solution to prolong lifespan. Simply immerse prepared electrode in sample, stir gently and record stabilized reading.
維護(hù)保養(yǎng)
建議每月用柔和清水清洗電極附著物，定期浸泡專業(yè)清洗液維護(hù)。不使用時(shí)應(yīng)套上保護(hù)套保持電極濕潤狀態(tài)。儀器應(yīng)存放于干燥環(huán)境，避免強(qiáng)電磁場干擾，長期停用后需重新活化電極。這些措施可顯著延長設(shè)備使用壽命。131729
Monthly maintenance includes gentle rinsing and periodic cleaning solution immersion. Protective cap should maintain electrode moisture during storage. Keep in dry areas away from strong electromagnetic fields, with electrode reactivation after prolonged inactivity - these practices effectively extend service life.
