If it does not, you cannot recalibrate the thermometer. 0000008956 00000 n Accurate Fever Scanning with Infrared Forehead Thermometers: Issues, Solutions and How to Calibrate Technicians calibrating an infrared thermometer temperature gun Because of the COVID-19 pandemic, there is a lot of interest in measuring human body temperature. Forehead thermometers are a non-invasive system that uses infrared technology, providing the easiest and quickest measurements. To calibrate your infrared thermometer with an ice bath: Step 1: Fill a large glass to the very top with ice (crushed ice is preferred but not required). 190 38 First, there are those that have a nut or a screw for calibration. It has a large, easy to read screen with temperature guidance which changes the backlight from green to yellow to red depending on the temperature reading. 0000011896 00000 n Now it is time to place the thermometer in the cold water. 0000004044 00000 n Ӕ�},2�u�Ø�&�7�ls���z�FnBdS�و��L� F��������i��4�2YS� -z�!���OB��p��yb+l`X; ����� 0000013977 00000 n They are placed on the temporal artery of the forehead and measure the infrared heat that comes off of the head. 0000022780 00000 n Infrared thermometers cannot typically be calibrated at home, but they are known for their low drift.
