CatCon 6 delta

The analyzer consists of a Con 6 m measuring transducer and an intelligent CatControl 6 cationic filter. It is used for continuous operation of conductivity measuring.

The Con 6 m measuring transducer also offers the possibility of integrating flow measuring for monitoring the sample flow in the system of representative and VGB compatible sample analysis. For continuous use, the measuring transmitter can be equipped with a wide-range factory mains adapter (4-wire principle). Alternatively, a two-wire version is also available if a separate auxiliary voltage is not required. The ventilation integrated as a standard in CatControl 6 ensures bubble-free flow even in the start-up phase system.

The pH value is calculated by determining the differential conductivity according to the VGB standard, which provides low operating and maintenance costs. This is a reliable alternative to conventional pH determination using a glass electrode.

Necessary prerequisites for calculating the pH value:
   • use of only one alkalization medium
   • main NaCl contamination
   • pH values > 8
   • low phosphate concentration (<0.5 mg / l)
