Abstract
A heat tone sensor includes a housing with a gas inlet and with a gas outlet as well as a device for generating a gas stream of a gas to be tested between the gas inlet and the gas outlet. A measuring element, around and/or through which the gas stream flows, is configured to catalytically burn at least a portion of the gas stream and to send a measurement signal. The measurement signal indicates a quantity of heat released in the process.
