Abstract

A gas measurement system for measuring the concentration of gaseous and/or vaporous components of a gas mixture by means of a color change of at least one reaction substance on a reaction support unit, which is arranged in at least two light permeable channels in such a manner that the color change on the reaction substance can be detected at low expense on a large number of separate positions. The detecting unit which detects the color change can be designed as a digital camera with an electronic image converter or image sensor, and an imaging optics system (e.g., a lens system). Related systems, methods, apparatus, and articles are also described.
