The reading of the IR thermometer should match that of the reference thermometer within the stated specification. The good thing about black bodies is that they approximate non-existent ambient radiation and can give back a typical 0.95 emissivity value. With a high-quality infrared thermometer, you can take accurate measurements without any issues. Further in distance will increase the test area creating a larger diameter of surface area being tested. If, however, you get a result that is outside the listed accuracy specification, you … If you perform the test correctly, and your IR thermometer is accurate, it should read approximately 32.0°F within the stated accuracy specification of your thermometer. The Infrared Temperature Measurement System. Reputable thermometer companies include their instruments’ specs on the packaging. Infrared thermometer advantage and disadvantage. The infrared thermometer should be at or near the room temperature where the test will be conducted. : To test the accuracy of an infrared thermometer requires access to a stable surface of known temperature. -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. Also, the right adjustments need to be done depending on the kind of surface being measured. You can only use an infrared thermometer to measure surface temperatures, for it cannot measure internal temperature. Most common infrared thermometers are spot infrared thermometer type that measures the temperature at a spot on a surface. Use an ice bath- This method resonates around factoring in a liquid’s boiling point when calibrating your infrared Thermometer. How to check accuracy of infrared thermometer? Infrared thermometers are highly useful devices that are also efficient, meaning you can be assured of the results they deliver. Use a comparator at a stable temperature to know the accuracy of an infrared thermometer. Most ovens run pretty close to the temperature shown on their digital readout or analog knob. The signal is amplified and, using successive digital signal processing, is transformed into an output signal proportional to the object temperature. To correctly take a measurement, hold your thermometer perpendicular to the subject’s forehead at the manufacturer’s recommended distance. Avoid touching the sensor.

Infrared light works like visible light--it can be focused, reflected or absorbed. The great advantage of an infrared thermometer is recording body temperatures and checking the temperatures of liquids, foods, and rooms. An Infrared thermometer, also known as IR thermometer is a thermometer that is a non-contact type, which means it can measure a body’s temperature without making contact. However, the response time is from 3 to 5 minutes. It is essential to learn the basics before using this thermometer to prevent inaccurate readings for a number of different reasons. The accuracy needs to be between 0.1 and 0.2 degrees. 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 … Each body with a temperature above the absolute zero (-273.15°C = 0 Kelvin) emits electromagnetic radiation from its surface, which is proportional to its intrinsic temperature. Not only do infrared thermometer offer quick and accurate readings but also safety to the parties involved. Expect that most infrared thermometers won't need calibration. For an infrared thermometer to function well, there should be no presence of high humidity or dust. Regards, Bill Measurement of body temperature has become an essential diagnostic method for medical treatment. When there is a temperature change, this device creates a voltage hence communicating the temperature change. The first type is the glass mercury thermometer. Blackbody calibrators are very useful for calibration of … Several problems exist in the clinical operation. The following simple instructions should help you perform a field check of an Infrared thermometer at moderate temperatures: Ice Water Test: Fill a glass with ice and add only enough water to fill the gaps between ice pieces. 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 … How to calibrate the Infrared thermometer using an ice bath? To be accurate, infrared thermometers must be kept free of dirt, dust, moisture, fog, smoke and debris. An infrared thermometer has a lens that helps you focus on the desired object while infrared rays are used to measure the amount of heat generated by the body or an object. You will not regret this decision because infrared thermometers are quite handy, especially when it comes to picking up hot spots. Save my name, email, and website in this browser for the next time I comment. Strictly divided, medical-grade infrared thermometers have the highest accuracy requirements. You first determine the measurement deviation of the infrared thermometer from the correct temperature. However, the electronic device is affected by aging problems. Here are some of its disadvantages; Yes, they can work. Infrared Thermometer Accuracy – how to check accuracy of infrared thermometer? All of these questions above drive you crazy every time they occur to you. Hold the infrared thermometer directly over the top of the ice/water at a distance of about 3″. High-quality infrared thermometers never disappoint; their accuracy is unquestionable. The distance-to-spot ratio (D:S) is the ratio of the distance to the measurement surface and the diameter of the temperature measurement area. To test the accuracy of an infrared thermometer requires access to a stable surface of known temperature. Klein Tools IR5 Infrared Thermometer. These thermometers make it easy for you to measure distance, with precision, between two objects without touching them.
