According to the FDA, benefits of non-contact infrared thermometers include: The biggest limitation is that how and where non-contact thermometers are used can affect the measurement, according to the FDA. Coronavirus Disease 2019 (COVID-19) How to Protect Yourself and Others. Follow these guidelines from the FDA: Non-contact infrared thermometers should be used in a draft-free space without direct sunlight. As a large population is getting back to work or school after the Spring Festival, citizens in public places are requested to measure body temperature with a non-contact infrared thermometer, also called a forehead thermometer, to prevent and control the 2019-nCoV epidemic., 2 Centers for Disease Control and Prevention. The FDA recommends non-contact infrared thermometers be used when temperatures are between 60.8-104 degrees Fahrenheit and when relative humidity is below 85%. The Large Non-Contact Infrared Forehead Thermometer delivers easy-to-read fever results. The close distance needed between the person using the device and the person being evaluated can increase the potential spread of disease. Now that you have a better understanding of the process that is involved in an infrared thermometer, it is time to explain how to properly use this item. For example, if your thermometer has a distance-to-spot ratio of 12:1, it measures an approximately one-inch-diameter spot when it's 12 inches from the target (about 2.5 cm at 30 cm). Although they are considered to be less accurate than forehead, ear or digital thermometers, they pose the lowest risk of cross-contamination. All rights reserved. (2020).

It's important to know that the laser is only a pointer and not used for the actual temperature measurement. Non-contact thermometers have strict manufacturer guidelines and instructions for use that must be followed to ensure an accurate reading. For individuals, say, your family, calibrate the IR thermometer. A lens that has fogged when the thermometer is brought into a warm room from a colder environment can also affect accuracy. Remember that steam or dust can affect the accuracy of IR thermometers. When reading a person’s temperature, a non-contact infrared thermometer must be held perpendicular to the forehead at a specific distance. Guidelines For Using Non-Contact Infrared Thermometers. Keep the lens of your thermometer clean and free of scratches. Common uses for infrared thermometers in industry. Noncontact infrared thermometers offer a great combination of speed, convenience, and accuracy, but only when they're used correctly. More recently, with the outbreak of the 2019-nCoV epidemic, non-contact infrared thermometer guns have been broadly used as the most prevailing tool for scanning people in crowded places in hope of finding those who have elevated temperatures, the earliest symptoms of … Arduino Based Non Contact Infrared Thermometer | IR Based Thermometer Using Arduino: Hi guys in this instructables we will make a non contact Thermometer using arduino.Since sometimes the temperature of the liquid/solid is way too high or way to low and then its hard to make contact with it and read its temperature then in that scen… Reflective surfaces are less emissive than dull surfaces. They are so useful, easy, and even fun to use that they have become as common in kitchens as they have on factory floors. For example, if there is steam or dust in the between the target and the thermometer, some of the IR energy may be deflected before reaching the thermometer. (2020). (2020). Three-color backlight with high fever alarm. The measurement spot is always wider. They are so useful, easy, and even fun to use that they have become as common in kitchens as they have on factory floors. However, there are a few "gotchas" when using an infrared thermometer that can generate readings that are misleading or just plain wrong. Putting a piece of non-reflective tape (such as electrical tape) over the shiny surface or applying some flat paint gives you a target from which you can get a better measurement. COVID-19, What You Need To Know About Using Non-Contact Infrared Thermometers, © 2020. Background on temperature scanning with non-contact thermometers, How to Use the Fluke 67 MAX Clinical Infrared Thermometer, Calibrating a HART temperature transmitter, High resolution infrared inspection applications for preventive maintenance, 62 MAX+ Handheld Infrared Laser Thermometer, 572-2 High Temperature Infrared Thermometer, Finding faulty terminations in high power electrical circuits, Identifying fuses at or near their current rated capacity, Identifying problems in electrical switch gear, Monitoring and measuring bearing temperatures in large motors or other rotating equipment, Identifying "hot spots" in electronic equipment, Finding faulty insulation in process pipes or other insulated processes. Where you use your infrared thermometer can also affect its accuracy. Although non-contact thermometers have many advantages, there are also limitations and guidelines to consider. Do not touch the sensing area of the thermometer. As a large population is getting back to work or school after the Spring Festival, citizens in public places are requested to measure body temperature with a non-contact infrared thermometer, also called a forehead thermometer, to prevent and control the 2019-nCoV epidemic. The non-contact infrared body thermometer is a medical device designed to last for three years. You should be especially wary when measuring the temperature of shiny metal objects, but even reflections off of glossy paint can affect accuracy. Distance and positioning can also impact readings. While this thermometer may not be entirely no-contact, it is pretty close. For instance, if they are used in an environment that is too hot or cold, the readings can be inaccurate. Watch out for (and compensate for) shiny, "low emissivity" objects. Non-contact infrared thermometers can detect the presence of a fever, one of the earliest symptoms of COVID-19, and keep individuals from infecting others. Fortunately, these sources of error are easy to avoid or work around. hbspt.cta._relativeUrls=true;hbspt.cta.load(149400, '857c6cb1-8377-44ca-b433-bde84db08db5', {}); When deciding if an non-contact infrared thermometer is right for your health screenings, here are some questions to consider: Has your institution/employer implemented the use of non-contact infrared thermometers for health screenings? Finally, for highest accuracy, it's best to allow some time (about 20 minutes is usually enough) for your IR thermometer to come to the temperature of its surroundings when bringing the thermometer into surroundings that are significantly warmer or colder than where it has been stored. However, the simplest way to help calibrate a non-contact thermometer is to create an ice bath for the thermometer to measure.
