Pen-shaped pH Meter

The pen-type pH meter employs a composite structure combining a glass electrode and a reference electrode. It generates a potential difference by measuring the hydrogen ion activity in a solution, which is then converted by the circuit into a pH reading. It is used for rapid on-site detection of liquid acidity or alkalinity, making it suitable for mobile operations such as food processing and water quality monitoring.
Selection
When selecting a pen-type pH meter, it is essential to consider a measurement range that covers the commonly used 0–14 pH, with an accuracy of ±0.1 pH and automatic temperature compensation. Additionally, attention should be paid to the replaceable electrode design, a waterproof rating of the device body that meets the requirements of the usage environment, and the inclusion of calibration solutions provided with the equipment.
