The parameters of infrared temperature meters are analyzed. The composition of the system for collecting statistical information on the influence of environmental factors on the accuracy of measurements is proposed. Research software is offered. Measurement statistics are given. Ways to increase the accuracy of measurements with non-contact infrared thermometers are indicated. Mathematical and physical support of non-contact temperature measurement is offered, the analysis of parameters of infrared body temperature meters is carried out, the system for receiving the statistical information for revealing of factors of influence is developed, the analysis of results is carried out.</p><p><strong>Originality. </strong>An updated formula for determining body temperature is proposed, which contains the following parameters: specific constant for a particular device, which depends on the optical focusing system and the absorbing material; the degree of radiation of the object, which depends on the material of the object whose temperature is measured; the absolute temperature of the object being measured; absolute ambient temperature; reflected radiation from the environment; absolute temperature of the pyrometer sensor housing..</p><p><strong>Practical value.</strong> &nbsp;The paper offers recommendations that can significantly increase the accuracy of measurements in the design of systems containing infrared thermometers.</p> ER -
