Multi-paraMeter pH conductivity Meter

The multi-parameter pH conductivity meter obtains pH values by measuring the hydrogen ion concentration in a solution using a glass electrode and determines conductivity by measuring the ionic conductivity with a conductivity electrode. It is used to monitor water acidity, alkalinity, and ion content, enabling real-time detection of solution characteristics in wastewater treatment and chemical production processes.
Selection
When selecting, focus on the measurement range covering actual needs: a pH range of 0–14, and conductivity selected based on solution concentration, such as 0–200 mS/cm. Consider automatic temperature compensation and check the corrosion resistance of the electrode material. Confirm that the instrument’s protection rating suits the usage environment and supports data storage and output interfaces.
