ABSTRACT:
An electrochemical gas sensor with at least two electrodes, with an electrode holder and with an electrolyte in a housing made of an electrolyte-impermeable material is improved in terms of its ease of handling and durability, without compromising the quality of the measurement. The otherwise closed housing has only one inlet capillary and outlet capillary each for the gas to be measured. A heater is provided which forms a gap with the working electrode arranged above the inlet and outlet capillaries. The heater is arranged in the housing in the flow path between the inlet and outlet capillaries. The gas sensor may be designed in the form of a miniaturized, chip-like component.
