Application Specific pH Testers
High purity water used in power generation, semiconductor manufacturing, and other industries can be difficult to measure due to the ability of carbon dioxide (CO₂) to diffuse into water and form carbonic acid (H₂CO₃). Carbonic acid quickly dissociates into hydrogen ions (H+) and bicarbonate ions (HCO₃-). These ions will increase the conductivity and decrease the resistivity of the water. In order to measure high purity water accurately it is necessary to perform a continuous flow measurement. HI98197 uses the HI763123 four-ring probe with a threaded connection that is screwed into a stainless-steel body flow cell. The flow cell is then connected to a water source to more accurately determine the conductivity or resistivity without exposure to air. HI763123 is an ideal meter for monitoring the efficiency of a mixed bed resin or equivalent system that produces high purity water of 18.2 Mω•cm at 25℃.
