Application Specific pH Testers
- PEI body
- For ultrapure resistivity water measurements
- Threaded connection to HI605453 Flow Cell for Ultrapure Water
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℃.
