CARBON DIOXIDE CONCENTRATION MEASURING DEVICE

摘要

PURPOSE: To inform of the concn. of carbon dioxide in exhalation by sound corresponding to the concentration. CONSTITUTION: A carbon dioxide concn. measuring device detects the signal changing corresponding to the concn. of carbon dioxide with the elapse of time from breaching gas to calculate the concn. of carbon dioxide and is constituted of a carbon dioxide concn. operating means 7 detecting the max. value at every exhalation from the concn. signal corresponding to the calculated concn. of carbon dioxide and comparing the same with the concn. signals corresponding to a plurality of predetermined concn. ranges to output control signals different at every concn. ranges and an information means 12 emitting the sound corresponding to the concn. of carbon dioxide on the basis of a control signal.
