The hikvision ebt510 is a handheld thermal imager which can be used to screen for elevated body temperature. Key features of the uss tic 500 include 384 x 288 pixel sensor body temperature detection with abnormal temperature alarm automatic exposure control and automatic white balance face temperature measurement mode that intelligently analyzes face targets and measures body temperature support for multiple alarm linkages dual light temperature measurement linkage and the ability to draw. Any infection that is detected early can help to minimize the risk of other employees becoming infected. How do we screen for elevated body temperature. Up to 1280 x 960 pixels resolution with testo superresolution and good thermal sensitivity. When screening for body temperature on the face the most reliable focal point for temperature measurement is the eye canthus or tear duct.
Elevated body temperature ebt measurement fever is a non specific symptom but it is one of the best early screening tools for infections such as the coronavirus. The normal body temperature for an adult is around 986f 37c but every persons baseline body temperature is slightly different and may consistently be a little higher or lower. Thermal imaging is an excellent non contact screening tool to detect people with elevated body temperature if used correctly. As a means of helping to prevent the spread of the coronavirus covid 19 many institutions have begun to institute thermal imaging cameras as a pre screening device. Until recently direct measurement of core body temperature required surgical insertion of a probe so a variety of indirect methods have commonly been used. This device identifies elevated body temperature ebt which could be indicative of a fever one of the symptoms of a viral infection.
Measurement of the spectrum of electromagnetic radiation from an ideal three dimensional black body can provide an accurate temperature measurement because the frequency of maximum spectral radiance of black body radiation is directly proportional to the temperature of the black body. Ear temperature measurement may be acceptable for observing trends in body temperature but is less useful in consistently identifying fevers. It has an accuracy of 09f accuracy over the range of 86 113f and measures from a distance of 32 feet 1 meter. This is known as wiens displacement law and has a theoretical explanation in plancks law and the bose. With the new testo elevated body temperature measurement the testo 890 thermal imager is perfect for identifying potentially ill persons.
