DIGOX WIN
Digox WIN is the PC user software for analysing the measurements and for diagnosis of the measuring instrument. Digox WIN runs under WindowsTM and meets all the requirements of modern data processing in the laboratory : - Read-outs from the data logger - Conversion to ExcelTM - Presentation of the data as tables or graphs
- Simultaneous online presentation and logging of
measurements

DIGOX 5 in the lab - Oxygen measuement in bottles and cans Oxygen measurement in bottles and cans is one of the most important measurements for quality assurance in drinks plants. The measurement also provides information about how well the bottling plant is functioning. The Digox 5 provides a system for total oxygen determination in filled bottles and cans which allows the calculation of the total oxygen from just one measurement of the dissolved oxygen. This procedure is based on the method described by K. Uhlig*. Phase parity is established in the sample between head-space and fluid phase with the Thiedig bottle turning device. Once the head space volume has been determined, the dissolved oxygen content is measured with the help of the Thiedig sampling device and the Digox 5. A simple calculation program then supplies the desired value for total oxygen in the sample. Digox WIN allows automation of the analysis through exploitation of its automatic data allocation.
The advantage of the method is its simplicity and the
absolute replicability of the measurements.
