CHAMBER FOR MEASURING THE SPECIFIC FLOW OF GREENHOUSE GASES FROM THE SOIL COVER Russian patent published in 2022 - IPC G01N1/22 G01N33/24 

FIELD: measuring technology.

SUBSTANCE: invention relates to chambers for measuring the specific flow of greenhouse gases from the soil cover. Essence: the chamber is made separable and consists of two parts: a cylindrical base (1) and an upper part (5). The lower edge (2) of the base (1) is pointed to facilitate the embedding of the chamber into the soil cover. The upper edge (3) of the base (1) is a U-shaped trough that serves as a hydraulic seal of the joint between the base (1) and the upper part (5) of the chamber. The upper part (5) is made in the form of a hollow cylinder, on the head of which a ventilation grille (6) is installed. One or more measuring windows (7) are located on the side wall of the cylinder, closed with reflective curtains (8). The hollow cylinder is made of transparent plexiglass, its outer surface is covered with reflective material.

EFFECT: increasing the accuracy of measurements of the specific flow of greenhouse gases from the soil cover.
