A detector for rapid response, quantitative determination of carbon dioxide in a gas comprising one or more components, each of which comprises a carrier with a surface to be exposed to the gas, said surface including ane indicating element of a predetermined sensitivity which gives a rapid response signal when exposed to a given concentration of carbon dioxide, the response signals produced when the component or components are exposed to the gas providing a rapid and progresssive quantitative determination of the concentration of carbon dioxide or any change with time of said concentration in the gas. |
