OPTICAL ABSORPTION GAS ANALYZER FOR MONITORING THE MAXIMUM PERMISSIBLE CONCENTRATION OF FREONS IN THE AIR OF WORKING AND LIVING AREAS
Annotation
The type of optical absorption gas analyzer for monitoring freons concentration in the air is specified. Characteristics of the gas analyzer to be developed are determined. A functional flow diagram of the optical absorption gas analyzer is presented. A method of modulating the pressure of the analyzed gaseous medium in the working chamber is developed and analyzed. A system of interference filters for the analyzer is designed.
