Water quality TDS Detector

A water quality TDS detector reflects water quality by measuring the total dissolved solids content in water. The principle is to detect the concentration of conductive ions in water, as dissolved solids are mostly electrolytes. It is used for rapid water quality testing in scenarios such as drinking water and industrial water.
Selection
When selecting, consider that the measurement range should cover common water quality standards, accuracy should meet usage requirements, and operation should be straightforward with easy calibration. Pay attention to electrode maintenance and temperature compensation functions, and choose the appropriate model based on actual water quality and application environment.
