Digox 602 dac
Acidic conductivity (cation conductivity) after removing CO2

In order to ensure a short start-up phase, it has to be differentiated whether an air-inleakage or a coolant leakage exists. Therefore, it is necessary to remove the carbonic acid from the sample. The conductivity after the CO2-degassing is now measured (degassed conductivity). If the conductibility value measured after degassing falls under the value of 0.2µS cm-1 then merely H+ and OH- according to the ion product of the water are still present as well as slip-induced anions as charge carriers. Thus, a cooling water hardness change can be ruled out and the start-up phase can be significantly shortened.

With the Digox 602 dac, you have a universal measuring instrument at your disposal. In the compact design, the specific conductivity and the cation conductivity are measured and the pH-value is calculated - the "degassed conductivity" is displayed.
