HI-763123 EC/resistivity probe for the HI-98197

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 MΩ•cm 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.
