What is a pH electrode?

A pH electrode is a sensor used to measure the acidity or alkalinity of a liquid, making it indispensable in fields such as science, industry, agriculture, and medicine. It primarily consists of a glass electrode and a reference electrode. When immersed in a solution, the pH electrode detects the pH value. The glass electrode features a sensitive membrane that generates voltage based on the concentration of hydrogen ions, while the reference electrode provides a stable voltage. pH electrodes are highly precise and reusable, making them essential for applications requiring accurate pH measurements.

Application of pH electrode

✅ Water Quality Management
pH electrodes are used to monitor the quality of water in drinking water supplies, industrial water, and environmental water. Maintaining the correct pH helps prevent harmful effects on people and ecosystems.
✅ Food Industry
In quality control, pH electrodes play a crucial role. For example, they measure the acidity of yogurt or sauces to optimize taste and preservation.
✅ Soil Analysis in Agriculture
pH electrodes measure soil acidity to create an optimal environment for crops. This enables appropriate fertilization and water management.
✅ Medical Field
By measuring the pH of bodily fluids like blood and urine, pH electrodes help evaluate a patient’s health. This enables early disease detection and effective treatment planning.
