Siemens SIPROCESS GA700 - Calomat 7; Module Design

To connect the reference gas supply and return lines use only such gas-contacted connecting
parts that are suitable for the connection and the reference gas.
The 󹪞ow rate of the reference gas can range from 0.1l/min to 1.5l/min. We recommend a
󹪞ow rate of approx. 0.5l/min.
For devices without 󹪞ow-type reference compartment, the reference cuvette is 󹪝lled with
nitrogen and hermitically sealed.
