TRADE SHOW PREVIEW 45 PET planet insider Vol. 15 No. 11/14 www.petpla.net Optical monitoring Berlin-based Dr. Thiedig GmbH & Co KG will be present- ing Digox Optical, its process measuring device designed for the optical measure- ment of oxygen in the beverage industry, and Digox 6.1m, which is a portable analyser for measuring oxygen in laboratory situations and for calibration. Digox optical, an in-line measuring device, is based on the dynamic fluorescence quench- ing optical procedure. It uses neither a membrane nor an electrolyte and measurement is independent of the CO 2 content and medium flow. It is directly installed in the pipe system and can operate in temperatures up to 130°C. Sensor replacement, which is required every 12 months, can be carried out quickly, directly in the line, without dismantling the device. The menu guidance system in the device software is supported through pictograms in the graphic display. Status information is displayed using dif- ferent colours in the display illumination, which measure values through a graphic trend display. Intelligent diag- nosis functions monitor wear. Digox optical is calibrated using the Digox 6.1 as reference measuring device, with- out removing the sensor. The measuring range of the new system is between 0 and 2,000 μg/l, the accuracy is +/- 1ppb. This system can be used in breweries for measuring tasks and process control including: water degassing, wort aeration, fermenting cellar, filtration, at separators, filling, and CO 2 recovery. Digox 6.1 is used for measuring oxygen in laboratories and in-line situations such as at the storage tank, after filtration, at the filler and for inspection when receiving tank deliveries from third parties. www.thiedig.com Dr. Thiedig GmbH & Co.
