231玻璃電極/231
產品概述
231玻璃電極是一款實驗室常用的pH測量電極，采用玻璃球泡敏感膜設計，適用于水溶液中的酸堿度檢測。其外殼為玻璃材質，具有優(yōu)良的化學穩(wěn)定性，可耐受常規(guī)酸、堿及溶劑，適合實驗室靜態(tài)或低電導率樣品的測量。電極需搭配參比電極（如232或217型）組成完整測量系統(tǒng)，兼容主流酸度計使用。測量范圍為pH 0-14，工作溫度5-60℃，具備高精度和重復性，堿誤差≤15mV，響應時間≤2分鐘（25℃條件下）。電極接口為BNC（Q9型），便于快速連接儀器。1312
技術特點
231玻璃電極的核心優(yōu)勢在于其敏感玻璃薄膜的響應性能。玻璃球泡經過特殊工藝處理，能夠快速穩(wěn)定地感知溶液中氫離子活度變化，理論斜率≥98.7%（25℃）。電極內阻≤250MΩ，確保信號傳輸穩(wěn)定。其設計適合常規(guī)實驗室環(huán)境，如水質分析、食品檢測及化工領域。使用時需注意避免強腐蝕性介質或機械碰撞，長期不用時可浸泡于3M KCl溶液中保持敏感膜活性。電極尺寸為Φ12×120mm，重量輕便，操作便捷。61121
應用場景
該電極廣泛應用于教育、科研和工業(yè)領域，如環(huán)境監(jiān)測中的廢水pH測定、制藥行業(yè)的反應液酸堿度控制，以及農業(yè)土壤分析。其兼容性允許與多種酸度計配合使用，尤其適合靜態(tài)或低流速樣品的精確測量。電極的玻璃外殼設計避免了塑料材質的有機污染風險，適合對測量環(huán)境要求嚴格的場景。7824
Product Overview
The 231 pH glass electrode is a laboratory-grade sensor designed for measuring the acidity or alkalinity of aqueous solutions. Featuring a glass bulb sensitive membrane and a glass housing, it offers excellent chemical resistance and stable performance in static or low-conductivity samples. With a measurement range of pH 0-14 and an operating temperature of 5-60°C, it delivers high accuracy (zero point pH 7±0.5) and repeatability. The electrode requires pairing with a reference electrode (e.g., type 232 or 217) for complete pH measurement systems and is compatible with standard pH meters via its BNC (Q9-type) connector. Its response time is ≤2 minutes under 25°C conditions. 11221
Technical Highlights
The 231 electrode’s performance stems from its specialized glass membrane, which achieves a theoretical slope ≥98.7% at 25°C, ensuring precise hydrogen ion activity detection. With low internal resistance (≤250MΩ) and minimal alkali error (≤15mV), it provides reliable signal output. The compact design (Φ12×120mm) suits routine lab applications, including water quality assessment and chemical process monitoring. Users are advised to store the electrode in 3M KCl solution when idle and avoid abrasive or high-viscosity samples to prolong service life. 3611
Applications
Ideal for academic, industrial, and environmental testing, this electrode is commonly used in wastewater pH analysis, pharmaceutical quality control, and agricultural soil research. Its glass construction eliminates interference from organic contaminants, making it suitable for sensitive measurements. The electrode’s compatibility with diverse pH meters enhances its versatility in both educational and professional settings. 7824
