Intended for modified atmosphere packaging-equipped thermoforming and tray-sealing machines, the Dansensor MAP Check 3 Vacuum online gas analyzer can be used with meat, poultry, fish and baked goods. Continuous data logging keeps in real time the residual oxygen records of every package produced; it measures gas content before the packages are sealed, taking a gas sample directly from the sealing die and giving an average reading of the residual oxygen for every cycle. If the gas levels exceed the preset limit, the packaging machine is automatically stopped. The analyzer has full datalogging capabilities, as well as USB and Ethernet connectivity.
