Water PH sensor Introduction
The industrial water PH sensor is a kind of water quality sensor to measure the PH value (hydrogen ion concentration index, PH) of the measured water, the instrument has automatic temperature compensation function. It is suitable for industrial sewage, domestic sewage, agriculture, and aquaculture in non-corrosive weak acid and alkali environment. The output signal is RS485, 4-20mA.

What does water quality test pH value mean?
When Water quality measurement pH means the negative logarithm of hydrogen ions in water. The pH is sometimes called the hydrogen ion index. The concentration of hydrogen ions in water can be used to determine whether water solubility is basic, acidic or neutral. Because the value of hydrogen ion concentration is often very small, it is not convenient to apply, so the concept of pH value is used as the indicator to judge the acidity and alkalinity of aqueous solution, and the negative pair value of ion concentration can express the magnitude of the change of acidity and alkalinity, so it is very convenient to apply.
What is a water PH sensor?
When water PH sensor, a sensor used to detect the concentration of hydrogen ions in the subject and convert it into a corresponding usable output signal, which is usually composed of a chemical locality and a signal transmission locality. PH sensors are commonly used for industrial measurements of solutions, water and other substances.
