DEVICE FOR LIGHT-HEAT MEASUREMENTS OF EMISSIVITY OF SOLID SURFACE Russian patent published in 2024 - IPC G01N25/20 G01J5/10 

FIELD: measuring.

SUBSTANCE: invention relates to measurement equipment, and in particular to light-heat measurements and measurements of emissivity of surface of a solid body in a room, to determine parameters of radiant heat exchange of a solid body. Device comprises housing (1) and nut (2) made of a material identical to the housing, collapsible nozzle (3) from aluminium and socket (4) for connection to the measuring equipment. Inner walls of the housing have a black coating, and a white light-emitting diode and a photoresistor are located inside the housing. Socket has five contacts, two of which are allocated for white light-emitting diode, two contacts for photoresistor, and one contact is spare, wherein the socket is made with polarity reversal protection in the form of a sleeve from zinc and copper alloys, inside which there is a socket providing one position for connection of the device.

EFFECT: elimination of thermal effect on the measured sample and use of a minimum number of parts of the device design with simultaneous reliability of measurements.
