Among professional thermometers and household thermometers, laser-targeted infrared thermometers are particularly widespread. Indeed, very simple to use, you can find them in food factories, among doctors, in cold rooms and industrial ovens, or even in large laboratories, to measure temperature effectively. Often chosen for its high precision, even at very high temperatures, the laser thermometer allows you to limit the risk of error in taking body temperature or ambient temperature, whatever it may be. Our experts explains to you how to use these heat radiation measuring guns, whatever your use.
What is a laser thermometer?
The laser thermometer is a non-contact infrared thermometer, also called pyrometer. It is an electronic thermometer that allows you to take the temperature of the body, food or a surface quickly and remotely. You can remember 3 advantages with the laser thermometer : it is not in contact with the person who potentially has a fever, with the product or the place, it allows you to take the temperature of a surface that you cannot easily reach and it only takes a few seconds to display the temperature directly on an LCD screen.
⚠️ Attention ⚠️ this is a measurement of the surface temperature. If you need to know the temperature of meat for example, it is recommended to use a penetration probe thermometer for more precise control.
The different uses of the laser thermometer
Take your temperature, check the temperature of an oven or check that baby does not have a fever, the laser thermometer is a multifunction digital thermometer. Let's return to the uses of a laser thermometer in its multiple applications!
The medical laser thermometer 🩺
Taking a patient's body temperature is essential for a doctor, a firefighter or hospital staff, in the event of fever but also in the event of hypothermia. There are two types of medical laser/infrared thermometers ; the forehead thermometer, for taking the temperature towards the forehead, and the ear thermometer to take the temperature through the ear canal. These thermometers are also very common at home, as they are ideal as baby thermometers especially to take the bath temperature or simply to check that children do not have a fever.
How to use a forehead thermometer?
To measure the temperature with a forehead thermometer contactless, nothing could be simpler; start by washing your hands and remember to place the thermometer in the room where the measurement will be taken at least 15 minutes before starting.
- Turn on the contactless thermometer
- Direct the probe towards the center of the forehead (it will also work on the temples) and within 5 cm of the area
- Press and hold the device button until you hear a “beep” sound indicating playback is complete.
Foreheads that are sweaty or covered in cosmetics or have scar tissue can cause inaccurate readings. For optimal and accurate measurement, it is recommended to keep the forehead area clean.
How to use an ear thermometer?
The ear thermometer is a very easy to use measuring device:
- Wash your hands then start by cleaning the ear canal if you have not already done so, the measurement will be even more precise and effective
- Place a suitable, sterile, disposable protective tip over the device probe to prevent infection
- After turning on the device, place the tip at the ear canal and press the button and hold it.
The temperature is displayed on the LCD screen within 1 to 2 seconds. Undoubtedly the best choice for taking the temperature of young children, you can use it even when your baby is sleeping.
The industrial laser thermometer 🏭
THE laser thermometers for industrial use are ideal for taking surface temperature measurements. They provide very precise temperatures remotely, whether in the case of industrial ovens or cold rooms for example. To use it is - once again - very simple. Allow the device to acclimatize for up to 30 minutes at ambient room temperature to allow optimal measurement of readings, as a thermometer transported from a warm room to a cold storage unit may show incorrect readings.
- Try to get as close as possible to the measured object and always make sure you are perpendicular to the surface being measured
- Simply point the thermometer at the target and press the measurement button to display the surface temperature on the LCD screen 1-2 seconds after the beep sound.
The laser food thermometer 🍔
The infrared food thermometer is ideal for compliance with food hygiene and safety standards because it allows measuring the surface temperatures of food. This eliminates the need to touch and potentially contaminate the food you are measuring, also avoiding a risk of cross contamination. These gun-shaped thermometers are compact, lightweight and always easy to use:
- Simply aim and pull the trigger to display the temperature of the item being measured (yes, that's it).
Choosing your laser/infrared thermometer
When choosing a professional thermometer, it is essential to think about the use “What measurements do I need to take with my thermometer?”. You can of course choose your thermometer based on its characteristics to get the most precise measurements.
To best choose your device for medical, food or industrial use, let yourself be guided by the advice of an expert !
