Remond RS485 Digital pH Sensor for Water
what is pH sensor?
pH refers to the acidity or alkalinity of an aqueous solution, specifically the concentration of hydrogen ions. The value varies from 0 to 14. Less than 7 is acidic, greater than 7 is alkaline, and equal to 7 is neutral.
pH sensor is a sensor used to detect the concentration of hydrogen ions in the measured substance and convert it into a corresponding usable output signal.
A pH sensor typically consists of a chemical component and a signal transmission component. PH sensors are commonly used for industrial measurements of substances such as solutions and water.
