Test gas cuvette for a device for measuring the concentration of a paramagnetic gas

摘要

With the present invention it is a very compact measurement gas cuvette for a device for measuring the concentration of a paramagnetic gas via the change is produced by a change in the magnetic field of the thermal conductivity of the paramagnetic gas is made available. Such a cuvette according to the invention has the following features: a) a bottom plate (1) carries a measuring element (1.4) for the detection of the thermal conductivity of the measurement gas, electrical supply leads, an electrical test gas cuvettes heater (1.2) and a temperature-dependent electrical sensor element (1.3) for the detection of the messgavküvettentemperatur, b) a channel plate (2) is for the gas in the region of the measuring element (1.4) and around the measuring element (1.4) is cut out around, c) a cover plate (3), which consists of a cuvette according to the gas is sealed toward the top, has at least two bores for the gas inlet - and the gas outlet in and out of the gas flow of the channel plate (2).
