pH-5015 high-temperature corrosion-resistant glass ph electrode

 Product Detail : pH-5015 High-Temperature Corrosion-Resistant Glass Electrode 

 Product Overview

The pH-5015 high-temperature corrosion-resistant glass electrode is specially designed for pH measurement in high-temperature and highly corrosive environments. It features a thickened cylindrical bulb design that provides excellent resistance to mechanical impact, acids and bases, and thermal shock. The dual-liquid junction structure and lead-free glass material not only meet hygienic requirements but also ensure measurement accuracy and stability.

 Measurement Principle

The pH-5015 electrode operates based on the principle of an electrochemical cell. The internal electrochemical reaction generates a potential difference, converting chemical energy into electrical energy, which is transmitted to the pH controller. After processing with the corresponding algorithms, the pH value is displayed. The electrode consists of a measuring cell and a reference cell, ensuring the accuracy and reliability of the measurement results.

pH-5015 High-Temperature Corrosion-Resistant Glass Electrode Application Areas

The pH-5015 high-temperature corrosion-resistant glass electrode is widely used in microbiology, pharmaceuticals, food and beverage, sugar production, chlor-alkali processes, mining and metallurgy, papermaking, pulp, textiles, petrochemical, semiconductor electronics, and various chemical processes and wastewater treatment. Its outstanding performance and stability ensure accurate measurement in these complex environments.

 Electrode Slope

The theoretical slope of the glass electrode at 25 °C is 59.16 mV, meaning that for every one pH unit change in solution, the glass electrode generates a 59.16 mV potential change. However, all glass electrodes cannot achieve the theoretical value perfectly. The slope of the pH-5015 electrode is generally above 95% of the theoretical value. Additionally, the mV difference per unit pH varies with temperature, and users can apply the relevant conversion formulas for potential difference correction based on temperature.

 Usage Precautions

- Electrode Wires: The electrode wires are specially shielded cables; do not cut or modify them to avoid inaccurate measurements or electrode damage.

- Soaking Environment: Avoid prolonged soaking in distilled water or protein solutions and prevent contact with organic silicone grease to protect the electrode.

- Maintenance: For long-used electrodes, the glass membrane may become transparent or develop deposits. In this case, rinse with dilute hydrochloric acid and wash with water.

- Electrode Replacement: If the electrode cannot be calibrated or provide normal readings, it indicates that it is beyond recovery. Please replace the electrode promptly.

- Waterproof Measures: The pH electrode wire is not waterproof; avoid contact with water to prevent damage to the electrode.
