Ph orp sensor probes utilize a similar combination sensor technology where they compare a reference solution to the actual sample.
Online ph sensors measure the hydrogen ion concentration and
online orp sensor instead measures the electron potential in the water. pH is a concentration measurement and ORP is not.
Water pH Sensor helps to measure the acidity or alkalinity of the water with a value between 0-14. When the pH value dips below seven, the water starts to become more acidic. Any number above seven equates to more alkaline. Each type of pH sensor works differently to measure the quality of the water.
As a professional
