  • Protection class IP67 and rubber housing

Combined CO₂ and DO meter: CboxQC


These combined CO2 and DO meters offer reliable quality control of finished packages, kegs, and casks as well as directly from the process line or tank. They guarantee fast and accurate determination of dissolved CO2 and O2 in beverages during production and bottling.

When combined with our filling devices, they let samples be taken directly from the package into the measuring chamber of the combined CO2 and DO meter, without losing dissolved CO2 during the sample transfer.
