Abstract
An apparatus and method measures the concentration of a gas. The apparatus comprises a radiation source (70) for emitting radiation onto the gas (79) to be measured, whereby the radiation source (70) is comprised of an anode (4) and a cathode (9), and as an emitting fill gas the same as the gas (79) to be measured; and a radiation detector (74) with which the radiation transmitted through the gas (79) to be measured can be detected. The cathode (9) functions as an electron emitter, and between the anode (4) and the cathode is connected such a low operating voltage that does not cause ionization or essential dissociation of the emitting gas. The design provides an approximate temperature tracking of the radiation source with the ambient temperature.
