FIELD: measuring equipment.SUBSTANCE: invention relates to measurement equipment and can be used for determination of total thermal resistance of textile materials. Disclosed is a control and measuring device for determining thermal parameters of textile materials, including heat accumulator, consisting of a gel in hermetic package, thermocouple with electrical indicator and sample of analysed materials. Hermetic package of heat accumulator is shaped as hollow cylinder, around vertical walls of which runs tape made of analysed materials. Heat accumulator is introduced into a pack of heat-shielding film placed in its turn in rectangular transparent housing with detachable or opening cover, additionally equipped with heating system, as well as system of determination of total thermal resistance of sample of analysed materials, composed of two thermocouples, switches, conductors and electrical indicator, in which EMF meter is used. Device is also equipped with stop watch and portable three-functional control-measuring instrument, providing for definition of local meteorological data, including barometric pressure, humidity and air temperature.EFFECT: technical result is provision of accuracy and reliability of measurement results.3 cl, 2 dwg |
