c-DGM
The Haffmans Portable Optical CO2/O2/TPO Meter c-DGM combines the internationally accepted determination of the dissolved CO2 content based on Henry’s Law with a highly accurate dissolved O2 and TPO measurement.
Haffmans state-of-the-art optical CO2/O2/TPO measurement technology is greatly improved compared to the traditional CO2/O2/TPO 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 included bumper protects the c-DGM against physical impact in harsh environments.
How it works
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 by using the interface cable. Data analysis can be done via Pentair Haffmans Navigator software. 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.
