Daruifuno's ASP121E analog PH Sensor employs a unique glass membrane electrode that is designed to interface directly with the solution being measured. This specific configuration enables the electrode to deliver exceptionally stable and precise pH readings, even in the challenging environment of pure water. The glass membrane electrode functions by responding to the hydrogen ion concentration in the solution, which in turn allows the sensor to accurately determine the pH level. The use of this specialized electrode technology makes the ASP121E a reliable and accurate tool for a wide range of pH measurement applications.?This pure water dedicated pH analog sensor is widely used in pure water manufacturing process detection, such as the electronics and semiconductor industries.
