FIELD: measuring equipment. SUBSTANCE: temperature sensor in the form of a reservoir with thermosensitive liquid is disposed in thermos flask which is placed into meteorological cabinet. The thermos is filled with salt solution. Upper part of the temperature sensor is secured in cork or foam plastic cover while its end contacting the flask bottom is provided with a slipped-on tube. EFFECT: considerably smaller thermal inertia of device, more reliable data on mean temperature within the test period and improved performance characteristics achieved by reducing the number of balls required for fixing the mean temperature within test period. 2 dwg
