Medical thermographs are devices which can be considered as non-invasive equipment. They are aimed at the detection of infrared radiation in order to provide a vivid image fixing the way temperature is difused over the body surface. Two factors influence skin temperature. First is conduction of heat generated in deeper layers of tissue to skin surface. Second one is the skin vasculature state. Fever screening system is the technique designed to fight so dangerous a condition as severe acute respiratory syndrome.

For the measurement of air pressure, the mercury barometer is the accepted standard. Aneroid barometers are also useful, particularly on ships and when used in the recording form called a barograph to show the trend of pressure change over a period of time. Barographs thermographs are part of a regular,typical set for weather stations equipment.
