Abstract
An optical multi-beam gas measuring apparatus is intended for detecting specific content in a gas of extraneous gases which absorb the same wavelength of the measuring radiation. The apparatus comprises a source of radiation and a gas vessel through which the gas mixture to be measured is conducted and the radiation is detected. The radiation directed through the vessel is picked up by an exchangeable detecting unit which contains a prism for splitting radiation which has passed through the gas mixture into several partial beams corresponding to the number of gas components to be measured. A prism is selected for this purpose and it is used in association with optical filters arranged in the path of the beams in conjunction with detectors which are electronically arranged for detecting the selected gases and measuring the value thereof.
