技术特点
231玻璃电极的核心优势在于其敏感玻璃薄膜的响应性能。玻璃球泡经过特殊工艺处理，能够快速稳定地感知溶液中氢离子活度变化，理论斜率≥98.7%（25℃）。电极内阻≤250MΩ，确保信号传输稳定。其设计适合常规实验室环境，如水质分析、食品检测及化工领域。使用时需注意避免强腐蚀性介质或机械碰撞，长期不用时可浸泡于3M KCl溶液中保持敏感膜活性。电极尺寸为Φ12×120mm，重量轻便，操作便捷。61121
应用场景
该电极广泛应用于教育、科研和工业领域，如环境监测中的废水pH测定、制药行业的反应液酸碱度控制，以及农业土壤分析。其兼容性允许与多种酸度计配合使用，尤其适合静态或低流速样品的精确测量。电极的玻璃外壳设计避免了塑料材质的有机污染风险，适合对测量环境要求严格的场景。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
