Always take the time to clean your infrared thermometer … With thermometers, this should include the temperature range the thermometer is designed to measure, the accuracy it should exhibit over that range, the speed with which it should exhibit that accuracy, and the resolution it will display (typically whole degrees or tenths or hundredths of a degree). You can verify this by using this thermometer continually and recording the readings to check for consistency. Make sure the lens is at a 90° angle and that the lens itself is centered over the ice/water per the illustrations shown here. With the help of a lens (input optics) the beams are focused on a detector element, which generates an electrical signal proportional to the radiation. A part of this so-called intrinsic radiation is infrared radiation, which can be used to measure a body’s temperature. The accuracy needs to be between 0.1 and 0.2 degrees. When taking measurements, keep in mind that measurement distance from the subject is different for every infrared thermometer – check the manual for your device to determine the correct distance.

How to check the accuracy of an infrared thermometer designed for measuring human body temperature: general process Place the Fluke 4180 non-contact infrared calibrator … -You can depress the trigger to obtain hidden temperature units.-Aim the laser point towards the object from which you want to collect temperature readings.-Stand as near as possible to the target object for pinpoint readings, unless you feel that it’s too dangerous for your health to get closer.-Pull the trigger to get temperature readings from the infrared Thermometer’s digital display. However, in some circumstance’s inaccuracy can occur, leading to misinterpretation of readings. Its sensing element is made of a thermistor or resistance detector. To get the best results possible, remember to: Know your IR thermometer's distance-to-spot ratio, and get close enough to the target so your thermometer reads only the area that you want it to measure. Here are some of the benefits you will reap from using an infrared thermometer; Just like any other device, an infrared thermometer also comes with its downside. Now that you know how to obtain prompt readings using a laser point thermometer, you need to focus on gaining more accuracy by way of calibrating it. Ensure the thermometer is being used on the correct site (forehead, wrist, etc) and setting (body, object, etc) per labeling. Infrared thermometer advantage and disadvantage. This is because you should not only understand its functionality but also be able to use it appropriately. Temperature measurements of moving or overheated objects and of objects in hazardous surroundings, Measurement without interreaction, no influence on the measuring object, Long-lasting measurement, no mechanical wear. Use a soft cotton swab and alcohol to gently wipe it clean if needed. The signal is amplified and, using successive digital signal processing, is transformed into an output signal proportional to the object temperature. You can take body temperature with this thermometer because that’s what it is designed for. Infrared Comparator Cup: (fig C) This device allows you to compare the accuracy of an infrared thermometer to a calibrated immersion type thermometer at a temperature other than ice/water. : To test the accuracy of an infrared thermometer requires access to a stable surface of known temperature. Inside the machined aluminum cup is a flat surface with a solid matte black coating. This thermometer is inexpensive and easy to use.
