It calculates the temperature from the infrared radiation produced by the subject being measured. It can be used for industrial purpose as well as for medical purposes. In medical purpose it is used to measure the core body temperature from forehead temperature depends on ambient air temperature that affects in the heat transfer coefficient. Heat transfers by conduction from the core body temperature and by convection from forehead to ambient air. The overall heat transfer coefficient is determined empirically depends on studies that had been made by measuring forehead temperature and core body temperature in various ambient air temperatures for hundreds of persons. The accuracy of the proposed thermometer is ±0.3 °C compared with Rossmax HA-500 device which depends on the accuracy of the studies and its results in various conditions.
