Process for determining the hydrogen content of nitriding gas mixtures in nitriding ovens comprises measuring the heat conductivity of the gas mixtures in a measuring cell connected to the working chamber

摘要

Process for determining the hydrogen content of gas mixtures in a working chamber comprises measuring the heat conductivity of the gas mixtures in a measuring cell (22) connected to the working chamber. Gas exchange is produced by diffusion between the working chamber or a line (24) connected to it and the measuring cell. An Independent claim is also included for a device for carrying out the process.
