    6 i7 The invention relates to devices for estimating gas odor, namely, physiological zero detectors for measuring odor intensity of various olfactory stimuli. A differential alfac tomometer is known, which contains injectors with jets mounted on a caliper, a device for stopping stimulation, an electronic control unit and a device for controlling the operation of jets lj. A disadvantage of the known device is the low accuracy of research, due to the impossibility of the simultaneous introduction of an irritant. Also known is a differential olfactometer containing tubes with jets, connected with an adaptation for the constant supply of stimuli 2.: However, this device is characterized by low accuracy of investigation, due to the impossibility of the simultaneous introduction of irritant. The aim of the invention is to improve the accuracy of research due to the simultaneous introduction of stimuli. The goal is achieved by the fact that a differential olfactometer, with holding tubes with jets, connected to a device for the constant supply of stimuli, is additionally equipped with a device to prevent dissipation of irritation, containing shells, covering tubes with jets, placed in the discharge chamber and connected by means of connecting tubes. element with an electric motor controlled by an electronic control unit, and two temperature sensors located inside the casing and connected through detectors op unit with electro Foot control. The drawing shows a differential olfactometer, general view. Differential olfactometer contains tubes 1 and 2 with jets 3 and 4, located on both sides of the caliper 5 for the nose. The nozzles 3 and 4 are connected to a device 6 for the constant supply of irritants. The device is equipped with a device to prevent the dispersion of irritants mounted on the nozzles 3 and 4 and made in the form of a casing 7 covering the tube of the nozzles 3 and 4. The casing 7 is connected to an electronic block 8 controlling the movement of the housing 7 along the nozzle tubes 3 and 4. The tubes 1 and 2 with the nozzles 3 and 4 are installed in the discharge chamber 9. Unit 8 is connected to temperature sensors 10 and 11, information from which is fed through amplifiers 12 and 13 to coincidence detector 14. Fixture 6 for the constant supply of irritants is provided with cartridges 15 and 16 with an odorous substance. Each cartridge is connected to a corresponding nozzle 3, 4 and a source of discharge 17. The housings 7 are connected by means of a connecting element 18 to an electric motor 19. The differential olfactometer operates as follows. The cartridge 15 is filled with the reference irritant, and another cartridge 16 is filled with the test gas. The experimenter presses against the nose support 5 and switches on the switch 20, by means of which the output of the coincidence detector 14 is connected to the input of the electronic control unit 8. When the experimenter makes an entrance, sensors 10 and 11 are cooled, and if this cooling occurs simultaneously, for example, for 5 ms, the control signal for moving the housing 7 along the nozzles 3 and 4 enters the electronic control unit 8. Said block 8 contains a device for capturing an adjustable delay for supplying the motion control signal to the motor 19, as well as a device for capturing the duration of the movement of the case 7. For example, if the delay in the movement of the case is 10 Ohms, the duration of the movement is 50 ms. This boost allows for olfactometric measurements at the moment when the experimenter’s olfactory sensitivity is at its maximum. When the casing 7 is moved to the extreme position, the reference stimulus and the test gas from the cartridges 15 and 16 enter the experimenter's nostrils. It is enough to adjust the pressure of the reference gas in such a way that it appears (the pressure is the same intensity of gas in each nostril. After that, the experimenter swaps the reference and test cartridges 15 and 16 of the gas. The experimenter makes measurements by the method of double measurement. The differential olfactometer provides a fast and accurate measurement odor intensity and the synchronous method of introducing stimuli. The reference and test gases are simultaneously introduced into the nostrils of the experimenter. Twomey olfactometer is the use of contrast enhancement between two olfactory bulbs. This contrast is maximal when the shift between the two feeding stimuli does not exceed a millisecond.
