Hanna Instruments EC/Resistivity Probe

HI-763123 EC/resistivity electrode for the HI-98197
The flow cell is then connected to a water source to more accurately determine the conductivity or resistivity without exposure to air. Hi-98197 is an ideal meter for monitoring the efficiency of a mixed bed resin or equivalent system that produces high purity water of 18.2 MΩcm at 25°C.
Designed for water professionals
The HI-763123 is used in conjunction with the HI-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.
About the HI-98197 Professional Waterproof Meter for Ultrapure Water
The HI-98197 is a waterproof, portable EC (conductivity) meter that has an expanded conductivity range from 0.000 µS/cm to 400 mS/cm, as well as TDS (Total Dissolved Solids), resistivity, and three salinity scales. This meter offers a quick connect four-ring probe and allows the user to adjust the nominal cell constant, HI-98197 is also ready to perform all three stages of USP <645> method required for EC measurement of water for injection.
