Pen-Style pH Meter

A pen-type pH meter forms a galvanic cell using a glass electrode and a reference electrode to measure the potential difference generated by the hydrogen ion concentration in a solution. This potential difference is then converted into a pH value through an electronic circuit and displayed. It is used for on-site rapid detection of liquid acidity or alkalinity, making it suitable for applications such as water quality monitoring, food processing, and chemical reactions.
Selection
When selecting a pen-type pH meter, consider a measurement range covering the common pH 0–14, accuracy meeting ±0.1 pH, and automatic temperature compensation. Check the replaceability of the electrode and the convenience of calibration. Pay attention to the waterproof rating and the device’s drop resistance, ensuring it matches the solution characteristics and operational environment requirements of the specific usage scenario.
