Particularly easy to use for professionals and individuals, the use of contactless thermometer has been democratizing for several years now. You will find forehead thermometers in some companies to prevent cases of fever, bath thermometers in homes where infants are growing up or high-precision non-contact thermometers to take the ambient temperature of industrial ovens or cold rooms. This infrared technology allows rapid, precise temperature measurement and its measurement range is generally wide. So, whether you need to check the body temperature of a patient or a hard-to-reach surface, it is necessary to choose the contactless thermometer best suited to your activity and use.
The contactless thermometer: definition and operation
Also called infrared thermometer, the non-contact thermometer is a device allowing the temperature of the surface of an object, the body temperature or an environment to be taken remotely (unlike conventional thermometers). Sometimes equipped with a laser allowing the user to aim precisely, the non-contact thermometer is also called a laser thermometer.
Concerning its operation, this electronic thermometer detects infrared energy (simply heat) and converts it into an electronic signal. The latter is then processed to produce thermal data then calculated as temperature value, and transmitted directly to the LCD screen of your thermometer. You are alerted by an audible signal when the temperature value reaches the highest precision point.
This measurement method can therefore be very precise provided it is well calibrated. The lens of the device must be clean, the measuring field free from any interference (dust or humidity) and the surface you wish to measure must not contain traces of rust or the like. Us temperature measurement experts also recommend that you check if possible with a contact thermometer with a penetration probe, for example, if the measurement does not seem reliable to you.
Applications of the infrared thermometer
The thermometer without medical contact 🩺
In the medical infrared thermometers, you will find the forehead thermometer, much more hygienic, ergonomic and precise than its cousin (the temperature is taken under the armpit). It is widely used by general practitioners, emergency doctors, etc. to quickly measure patients' body temperature. You can also find it in different companies since the recent health crisis in order to check employees' temperatures and limit the risks in case of fever. Less widespread but just as effective, the ear thermometer is the best ally of pediatricians for taking temperatures in babies and young children.
The industrial contactless thermometer 🏭
If you work in this field of activity you know that industrial infrared thermometers are used very regularly. From controlling the temperature of an oven or other equipment to measuring the temperature of a ventilation system, including checking mechanical equipment or electrical circuits (e.g.: electrical cabinets), the uses of 'A contactless thermometer in the industrial sector are very varied.
The thermometer without food contact 🍔
THE infrared food thermometers They are very widespread in food factories or in the kitchens of the best Parisian restaurants, where food is subject to particularly strict hygiene and safety conditions. THE contactless thermometer allows for strengthening controls on the packaging of packaged food products (provided that measurements are not carried out in air pockets).
The scientific contactless thermometer ⚗️
If it is not the thermometer most used in scientific research, the contactless thermometer still allows the detection of clouds for telescopes, the control of heating or cooling of materials with precision or the detection of hot zones during a fire.
The contactless household thermometer 🏠
Often called the baby thermometer, as part of the use of taking body temperature or bathing a toddler, the contactless thermometer is taking up more and more space in our homes. If we all had a rectal thermometer (now used more as an underarm thermometer), it is slowly starting to be erased by the new electronic thermometers.
Your contactless thermometer
You will have understood, for choose the ideal infrared thermometer for your activity and ultimately, the use you will have of it, you can base yourself on different criteria.
The choice of a temperature sensor must first be made based on the type of application, taking into account ambient conditions, temperature ranges and the desired measurement accuracy. You can of course choose your thermometer based on its characteristics, its functionalities (multifunction, recorder, memorization, waterproof, automatic shutdown, silent mode, etc.) or even its use. You can also consult our guide on how to use an infrared/laser thermometer to find out more.
