For these thermometers to be marketed the manufacturer must justify its correct and safe operation through calibration and precision tests beforehand. The infrared thermometer does not use a laser beam to measure a persons temperature but uses infrared rays that detect body temperature without impacting the retina. Power on the device and point it at the inside corner of the patients eye holding still. The temperature of two systems is the same when the systems are in thermal equilibrium. The difference between these two measured values taking into account clinical equalisation calculations gives the body temperature which is shown on the lcd display. Infrared temperature sensors measure the bodies outer skin temperature but whether that is a good indication of internal body temperature is a medical question and beyond the scope of this blog.
The temperature reading will display within 1 second. An infrared thermometer pyrometer such as the testo 830 can be used for temperature scanning rather than one that is inserted into the ear mouth or under arm. To properly use a non contact infrared thermometer to scan body temperature stand 5 15 centimeters away from your target. One factor which may influence the reading is ambient environment temperature. Many devices such as icis hotspot ir are battery powered. The company has been developing high accuracy infrared measurement instruments since 1947 and has been creating human body temperature screening systems since responding to the sars outbreak of 2003.
Temperature controls our quality of life and the measurement of different types of temperatures are inter related especially when utilizing infrared thermal imaging for human temperature screening. The farther away you are from your target object the larger the spot you will be measuring. An infrared sensor detects the highest measured value while a second sensor measures the ambient temperature. The degree or intensity of heat or cold with reference to some standard value. It measures the objects surface temperature rather than the internal temperature. One method to measure a persons surface temperature is with the use of non contact infrared.
The infrared pixel of 692 is 384 288 that is there are 110000 temperature points in a thermal image which is equivalent to measuring temperature with 110000 temperature measuring guns at the same time and the efficiency will be significantly improved. This kind of thermometer reads thermal radiation. The viralert 3 builds on ametek lands proven expertise in temperature technology. Non contact infrared thermometers measuring a persons temperature can be done in several ways. An infrared thermometer is actually reading the temperature above below or around where you see the laser and shoots out in a cone shape.
