Haffmans c-DGM CO2/O2 Gehaltemeter

The CO2 /O2 Gehaltemeter, type c-DGM, combines the internationally accepted
determination of the dissolved CO2 content based on Henry’s Law with a highly accurate dissolved O2 measurement. This state-of-the-art optical O2 measurement technology is greatly improved compared to the traditional O2 measuring instruments and doesn’t require frequent calibration. Its design allows for higher product pressure, making it suitable for the soft drink industry. Up to 10 different product types can be programmed into the device. The bumper protects the c-DGM against physical impact in harsh environments.

When the CO2 measurement is started, the O2 content is stored. Automatically,equilibrium is created, followed by the measurement of pressure and temperature.The dissolved CO2 content is then electronically calculated and displayed. The data can be securely transferred to a PC using the interface cable. Besides the combined CO2/O2 measurement, the c-DGM is suitable for single O2, continuous O2 and single CO2 measurements. Also the Total Package Oxygen (TPO) value, based on the Uhlig method, is calculated in the CO2 / TPO measuring mode and the single TPO measurement.

• At-line, sampled directly during the production process
• Laboratory, after the production, sampled from a variety of bottles or cans
• TPO calculation from bottles or cans using sampling device ISD-special
