MULTICHANNEL GAS ANALYZER AND GAS ANALYSIS METHOD Russian patent published in 2022 - IPC F17D5/00 G01N21/00 

FIELD: measuring equipment.

SUBSTANCE: present invention relates to measuring devices, in particular to devices for measurement of gas parameters for analysis of air components. A multichannel gas analyzer includes a case, in which at least two gas inlets are made. A heat-insulating casing is located inside the case. Inside the heat-insulating casing, there are at least two gas sensors, at least one temperature, humidity, and pressure sensor, and an electronic board of the gas analyzer. At the same time, each of gas sensors includes at least an inlet, a sensitive element, and an electronic board of the sensor. The sensor inlet is connected to the gas inlet, forming a gas inlet channel, and the board is connected to the electronic board. At the same time, the board is configured with the possibility of taking into account sensitivity of each sensor to other gas parameters.

EFFECT: increase in the reliability of a gas analyzer during outdoor operation in a wide temperature range, in particular due to an increase in its protection from external impacts, as well as due to an increase in the accuracy of measurement due to a decrease in a measurement error.
