A software option for the Digox 6.1 allows a simple and fast measurement of the TPO in beer. The oxygen uptake at the filler, the concentration in the headspace and the TPO (EBC method) is automatically calculated. Methods can be configured according to specific applications: type of bottles and number of bottles (shaken, not shaken). The operator is guided by the display of the Digox 6.1: prepare bottles, turn bottles, measure, calculate the TPO, display results. If e.g. the time is exceeded, this will be displayed and recorded. All data can be transferred to a PC for an interpretation of the results.
