FIELD: testing equipment.
SUBSTANCE: invention relates to the field of testing devices for tightness and can be used for testing tightness of the places of sealing of the measuring lines of temperature sensors. Essence: stand contains bath (1) with liquid (2), platform (3) installed with the possibility of moving relative to the liquid mirror, a supply system of compressed gas. Product mounting and sealing unit is located on platform (3). In addition, the stand is equipped with glass (5) with pipe (6) connected to the compressed gas supply system. Glass (5) is sealed around measuring part (7) of the thermocouple to create an overpressure around it. Mounting and sealing unit is made on platform (3) in the form of opening (10) under the body of the comb of the thermocouple and the means of its fixation. Stand contains a liquid organic dielectric with normalized properties as liquid (2) based on one of the group of lower alcohols: methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol.
EFFECT: technical result: determining quality of the soldering of the places of seal of the measuring lines in the case of the thermocouple comb prior to its mounting on the product.
