FIELD: devices for studying the physical-chemical properties of soils.
SUBSTANCE: device includes a pipe (1) with soil fixed between the injection chamber (2) and the outlet chamber (7), a unit (9) for processing and displaying the measurement results. The injection chamber (2) is equipped with a hermetic valve (3), temperature meter (4), a pressure regulator (6) and the first continuous gas analyzer (5). The second continuous gas analyzer (8) is installed in the outlet chamber (7). The outputs of the first and second continuous gas analyzers (5, 8) are connected to the inputs of the unit (9) for processing and displaying the measurement results.
EFFECT: improving the accuracy and information content of determining the coefficient of diffusion of gas through the soil.
