Gas measurement system

摘要

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.

主权项

1. An apparatus comprising:
a housing defining a slot; a friction bearing within the slot configured to couple to a reaction support unit, the reaction support unit comprising at least two light permeable channels configured to receive at least one reaction substance, the at least one reaction substance changing color in presence of at least one particular gaseous or vaporous component; a gas conveyance device configured to convey gas through at least one channel of the reaction support unit; an optoelectronic detection device configured to detect a color change of the at least one reaction substance on the reaction support unit during and/or after the conveyance of the gas mixture, the color change being detected in the direction of flow of the gas mixture through the at least two channels in at least two separate positions, the optoelectronic detecting device comprising a digital camera having an image converter or an imaging optics system; an evaluating device configured to evaluate the data detected by the optoelectronic detection device; and a sensory feedback device configured to provide sensory feedback characterizing the data evaluated by the evaluating device.
