Digox 602 dac

Analyser for the continuous measurement of the specific, cation and degassed conductivity in the water-steam cycle of power plants.
In order to ensure a short start-up phase, it has to be differentiated whether an atmospheric leakage 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).
The analyser Digox 602 dac enables very short start-up times of the power plant.

ADVANTAGES

Degassing and measurement at normal temperature

No heating up, therefore: no gas emissions of other volatile acids

No inert gas required, air-conditioning by means of CO2 absorber mass

High gain of degassed carbonic acid

Interpolation of measuring results to actual CO2 content

Short response times

Simplified flow adjustment with flow stabilizer

Available as “DAC basic”: Retrofit option for existing measurement of the cation conductivity
