    when brought into contact with the indicator medium that is expanding under the action of heat, is made on the rod 11 with a frost-covered surface, the rod 11 being located in the longitudinally extending hole 12 of the housing 10. In combination with the passage just longitudinal hole 12, the rod 11 forms a capillary channel , which the
    O passes from the bottom of the tank 13 to the upper end 14 of the housing 10. The upper end is sealed by means of the cover 15, and the fixing rod 11 is relative to the hole 12. The nyxi reser tank 13 is filled with a wedge under the action of heat with indicator medium into which the lower end of the rod 11 is immersed .The upper surface of the indicator medium is indicated by the position 16.
     Further, the housing 11 is provided with a temperature scale 17, which is preferably printed on the outer surface of the housing 10. The scale marks 17 are spaced from each other so that the distance between the two marks corresponds to a predetermined increase in temperature, which causes a corresponding rise in the indicator medium surface 16
    inside the capillary channel between
    rod 11 and the inner surface of the rod 12.
    The housing 10 may be made of the same material as the parts of the thermometer 2 and 3 (figures 1 and 2). Further, the indicator medium 13 may be of the same type as the indicator medium 9 of the first embodiment. The surface of the rod 11 is frost-coated or matted preferably in accordance with the process that is described, and the material of the rod 11 is preferably identical to the material
    hulls 10. The lid 15 may be made on hot melt glue, solvent based glue or catalytic hardening glue. Alternative rod 11 and housing
    g 10 can be welded together, for example, using ultrasonic welding. The rod 11 may have any suitable cross-sectional profile. Three alternative cross sections
    rod 11 is shown in figa, b and c. Fig. 4a shows a rod 11 with a round cross-sectional shape located inside the longitudinally extending channel 12 of the housing 10. In Fig. 4c

    a rod 11 is shown with a triangular cross-sectional shape, and FIG. 4c shows a rod 11 with a square cross-sectional shape. However, other configurations are possible.
    When the indicator medium is heated, it rises in the capillary channel between the inner surface of the longitudinal channel 12 and the outer surface of the frost-covered or matted rod 11 to the level corresponding to the temperature the medium undergoes. The indicator medium rising in the capillary channel causes the milky hue to disappear. the surface of the rod 11, thus causing a detectable and irreversible change in the light-penetrating properties of the capillary channel wall. The change is clearly visible through the transparent wall of the housing 10.
    When assembling the embodiment shown in Fig. 3, a predetermined, precisely metered quantity of indicator medium is introduced into the lower reservoir 13 through the longitudinal channel 12. The inner surface of the said channel is completely smooth and, therefore, no substance of the indicator medium is deposited on the said inner surface. . Preferably, the indicator medium is introduced in the molten state, the rod 11 is located in the channel 12 at a predetermined level relative to the housing 10, the rod 11 is fixed relative to the housing 10 by means of a cover 15, which also serves to seal the thermometer.
    When filling the tank 13 with indicator medium, the most important point is the dosing is extremely accurate. of the indicated indicator medium, since the volumetric expansion of the indicator medium is determined by the volume of the indicator medium, the thermal expansion coefficient of the said medium and the increase in temperature, and thus the maximum temperature is measured. The volumetric expansion of the indicator medium is converted into a linear movement of the surface 16 of the indicator medium inside the capillary channel. Therefore, the thermometer shown in FIG. 3, in which frost-covered or frosted
    86
    the rod can be adjusted or calibrated in a very simple way. The precisely metered volume of the indicator medium is introduced into the lower tank 13 at a predetermined exactly fixed temperature in the molten state. Frost coating or frosted rod 11 then
    is introduced into the channel 12 and immersed in the indicator medium contained in the lower tank 13 until the surface 16 reaches the mark 17 corresponding to a precisely fixed temperature. After that, the rod 11 is cut off at the upper end of the housing 10 and attached to it by means of a cover 15. Alternatively, the thermometer shown in FIG. 3 can
    be calibrated (figs, 7, 8 and 9). The embodiment shown in Fig. 3 may also be provided with protection against damage to the thermometer prior to its use in accordance with Fig. 7,
    8 and 9.

    can be modified so that the rod is used for alignment or calibration. In this embodiment, the capillary channel 6 must be enlarged to a patsially large opening corresponding to the opening of the channel 12 of the variant shown in FIG.
    The third embodiment of the invention (FIGS. 5 and 6) includes two plate-like
    parts or parts labeled 18 and 19 respectively. The two parts are adapted to be assembled into one elongated body using a suitable method, for example, by gluing
    or welding, such as ultrasonic welding. The two parts are made of transparent plastic, such as polyvinyl chloride, polystyrene, polyacrylonitrile styrene, polymethylmethacryl or
    polycarbonate. However, one of the two parts can be made of another material, such as aluminum, to increase the temperature sensitivity of the thermometer. Part 18 is supplied

At the lower end of the elongated body 22 there is an annular groove 25, and at the lowest end, in place 26, the body
    22 has a reduced diameter with respect to the entire diameter of the housing 22. Further, the housing 22 has a frusto-conical inlet 27 at its lower end. Although the tank housing 23 may be made of the same material as the housing 22, it is preferable to manufacture the tank housing 23 from a material with good thermal conductivity, such as aluminum. A cold stamping process can be used to manufacture the tank body 23. Inside the tank
