The new infra-red gas analyser for measurement of CO s concentration described uses a focussed, dual optical path. The 2 W radiation source is a heated alumina bead and a cooled lead selenide photoconductive detector measures the difference in radiation absorption at 4.26 tzm by the gas in sample an
