摘要： A sensing device is provided. The device comprises a gas permeable member, a sensing member and optical means.The gas permeable member is arranged to receive gas from a substance to be tested. The sensing member is located adjacent to the gas permeable member and comprises a sensing substance. A property of the sensing substance is modified when it is brought into contact with the gas received by the gas permeable member.The optical means comprises a light source which is arranged to irradiate the sensing substance together with a first sensor which is configured to detect a change in the aforementioned property of the sensing substance.

摘要： A rheometeris disclosed for determining flow characteristics of a fluid. The rheometer comprises a circuit in which the fluid is arranged to flow. The circuit comprises a duct and a plurality of flow elements, each comprising a flow environment arranged in fluid communication with the duct. The flow environment of each element is arranged to convey fluid from an up-stream position to a downstream position of the respective flow element. The rheometer further comprises pressure sensing means arranged to determine fluid pressure at the upstream position and the downstream position of each of the plurality of flow elements. At least two of the plurality of flow elements comprise different flow environments for the fluid such that the rheometer can determine the flow characteristics of the fluid at a particular instant in time.
