In our constant quest to make life more convenient and precise, technology plays an undeniable role. Among the innovations that are revolutionizing the way we measure temperatures, the infrared thermometer stands. This tool, contactless and ultra-fast, has become a must-have in many areas. But how does it work and why should you consider owning one? Let's dive into the fascinating world of infrared thermometers.
What is an infrared thermometer? : An infrared thermometer is a device that measures temperature from the infrared emission of an object. Unlike traditional thermometers which require direct contact with the substance or object to be measured, infrared thermometers allow remote measurement, without any contact.
How does it work ? : When an object heats up, it emits energy in the form of infrared radiation. The infrared thermometer detects this radiation, converts it into electricity, then into temperature. Everything is done in a fraction of a second, offering almost instantaneous reading.
Understanding emissivity and its role in infrared measurement:
Emissivity is a key concept for obtaining accurate measurements with an infrared thermometer. It determines how a material emits thermal energy in the form of infrared radiation.
- What is emissivity? Emissivity is a coefficient, between 0 and 1, which describes the capacity of a surface to emit radiative energy compared to a perfect black body (which would have an emissivity of 1). In other words, a material with an emissivity of 0.8 emits 80% of the thermal energy that a black body would emit at the same temperature.
- Why is it important for infrared thermometers? The accuracy of an infrared thermometer largely depends on correctly taking into account the emissivity of the surface being measured. If the emissivity set on the thermometer does not match that of the object, it can result in inaccurate readings.
- How to take emissivity into account? Many infrared thermometers offer the ability to adjust the emissivity to match that of the surface being measured. Some surfaces, like polished metals, have low emissivity, while others, like human skin or wood, have higher emissivity. To obtain an accurate measurement, it is essential to know and correctly adjust this value.
- Practical advice:
- When you do not know the emissivity of the surface, consult the emissivity tables provided by the manufacturers or available online (see Emissivity table).
- For highly reflective surfaces, consider using masking tape or matte black paint to create an area with known, measurable emissivity.
- Keep in mind that emissivity can vary depending on temperature, surface area or angle of measurement.
Main advantages :
- Sans contact : Ideal for measuring the temperature of moving, hot or electrified objects without risk.
- Speed : Results are displayed almost immediately.
- Versatility : They can be used in a variety of environments, from kitchen to industrial to medical check-ups.
- Hygienic : Their contactless use avoids cross-contamination.
Application areas :
- Medical : Rapid measurement of body temperature, especially useful in times of epidemics.
- Culinary : Control the temperature of food without touching it, ideal for chocolatiers or pastry chefs.
- Industrial : Monitoring of machines, motors or electrical systems.
- Automobile : Rapid diagnosis of problems by detecting overheated areas.
