Hanna Instruments-763123 EC/resistivity probe for the Hanna Instruments-98197
Designed for water professionals
The Hanna Instruments-763123 is used in conjunction with the Hanna Instruments-605453 stainless steel body flow cell which is connected to a water source to more accurately determine the conductivity or resistivity without exposure to air.
High purity water used in power generation, semi-conductor 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 (HCO-3). 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.
