An improvement in a measuring apparatus for the quantitative determination of a component of a gas sample. The apparatus takes a charge of a predetermined volume of the gas mixture into a metering pump which then pushes it through the absorption unit which adsorbs or absorbs a component of the gas. A probe is used for the intake of the gas and the probe has in the region of its intake opening a thermocouple. In addition, from the cable leading from the thermocouple a reference sensing device such as a second thermocouple is placed in differential connection. A single converter is used for indication of the temperature value and a microcomputer may be used to substantially automate the process.
