Eich-Anordnung mit Gehäuse

摘要

A calibration system (11) comprising a sensor cassette (13) including at least one sensor (29,31,33) to be calibrated and a housing (15) having a liquid passage (41) including a chamber (43). The housing is coupled to the sensor cassette to place the liquid passage in fluid communication with the sensor cassette. The housing has a gas injection passage (51) through which a gas can be injected into the liquid passage to mix with a calibration liquid (16) in the housing. A gas vent (55) vents the gas from the housing. Porous media (131,135) is provided in the chamber. The gas and calibration liquid pass through the porous media, and the porous media assists in rapid mixing of the gas and the calibration liquid.
