Portable pH Conductivity Meter

The portable pH conductivity meter determines the pH value by measuring the hydrogen ion concentration in a solution using a glass electrode, while also utilizing an electrical conductivity cell to detect the ion conductivity and calculate the electrical conductivity. It is used for on-site rapid detection of water acidity, alkalinity, and ion content, and is suitable for fields such as environmental monitoring, aquaculture, and wastewater treatment.
Selection
When selecting, consider a measurement range that covers actual needs, accuracy that meets testing standards, and the inclusion of temperature compensation. Check the instrument's protection rating to ensure it suits the operating environment, and pay attention to the compatibility of the electrode material with the liquid being measured. Compare the ease of operation and calibration methods across different brands, and make a choice based on the budget.
