As a support for the thermometer, when it is placed on the supporting surface, use the lower end part of the pipe (thermometer body). The execution of the thermometer body in the form of a pipe provides a faster achievement of an equilibrium temperature by a thermometric liquid, which is explained by the intense influence from the medium side on the thermometric liquid both from the side of the through cavity of the pipe and from its outer side.

Indicator medium (indicator substance) 3 can be formed, for example tinted with ethyl alcohol (any medium known from and used in the manufacture of thermometers can be used as an indicator medium). Wall 1 may have a thickness of 4-40 mm. The width (if the pipe has a round shape, then the diameter) of the pipe is 30-1000 mm.

The thermometer works as follows.

The thermometer measures the temperature of the environment or substance by placing the thermometer in the environment or substance. Under the influence of the ambient temperature or the substance, the volume of the indicator medium 3 changes, and as a result of the volume change, the height of the column of the indicator medium in the cavity 4 changes. The value of the temperature of the substance and temperature are determined by the position of the edge of the column of the indicator medium 3 in the cavity 4, relative to scale 5 which measure.
