The Gas Control 50 from Witt Gas Controls LP, Alpharetta, GA, lets you monitor the composition of the most common gas mixtures and can be installed ex-works for gas mixers or in a separate housing for retrofits. The device provides gas analysis as well as control and analysis and features a multicolor touchscreen, an integrated circular buffer to record all user inputs and measuring results, a USB interface, and the ability to define alarm limits via touchscreen or Web Visio. When the limits are exceeded, the processing unit switches an isolated contact. The gas control unit also lets you set up the fully automated gas analyzer calibration.
