Product description

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.
