SETT VID TESTNING AV GASANALYSAPPARATER SAMT ANORDNING FOR GENOMFORANDE AV SETTET |
摘要 |
A method for checking gas analysis devices in respect of their sensitivity and their response and regeneration behaviour with respect to time, wherein a reproducible quantity of the measurement component is produced at a predetermined production rate, for a period of time which is guided entirely or at a constant proportion as a concentration pulse to the measurement element of the gas analysis device. For the production of the measurement component a chemical or electro-chemical reaction or even a thermal reaction is used. The time interval can then be conveniently controlled. A decisive advantage with toxic measurement components is that the gas production takes place in all cases for only a short time during the test procedure. |
