The Exergen Temporal Artery Thermometer is a non-invasive system that can easily be used for newborns, infants, children or adults. Temperature is taken by gently placing the thermometer on the forehead while it measures the balance between the tissues warming from arterial blood and tissues cooling from the environment. This unique design allows you to take the temperature of the skin surface over the temporal artery and uses advanced infrared technology to do so. Features Temporal artery temperature scanner Temperature is taken by placing the thermometer over the temporal artery so temperatures can be read through non-invasive procedures. This is the gentlest way to take a baby’s temperature. Infrared technology Temperatures are read through infrared technology to provide accurate temperature readings. The thermometer first scans and captures naturally emitted infrared heat, then measures the ambient temperature of the site where the temperature is being taken. Arterial heat balance software then synthesizes these readings to determine body temperature. Clinically tested This thermometer has been clinically tested for accuracy in comparison to rectal thermometers. It is accepted for use in major hospitals so you can feel safe using it on anyone at home. Patented software The patented software provides arterial heat balance. The process accurately measures the balance between the tissues warming from arterial blood and tissues cooling from the environment. Document Links Instruction Manual Product Description The Exergen Temporal Artery Thermometer is a totally non-invasive system with advanced infrared technology providing maximum ease of use with quick, consistently accurate measurements. Advanced, patented technology measures temperatures with a gentle stroke across the forehead. The Exergen Temporal Artery Thermometer has been clinically tested for accuracy compared to rectal thermometers and temperature sensors inserted in the heart during course of patient treatment and accepted for use in major hospitals, making it the ideal thermometer for use with newborns, infants, children or adults. The Exergen Temporal Artery Thermometer has patented software, providing arterial heat balance. This unique process determines temperature by accurately measuring the balance between the tissues warming from arterial blood and tissues cooling (warming) caused by heat loss (gain) to the environment.
