How Infrared Thermometers Work
Infrared thermometers function by utilizing a lens system to concentrate the infrared radiation emitted from a surface onto a detector. This infrared light emitted from all surfaces with a temperature above 0 K, and the intensity of the emitted radiation is influenced by the surface temperature, with higher temperatures leading to increased radiant energy. The key components involved in the operation of an infrared thermometer encompass a lens that focuses the infrared light emitted from the object and a detector, such as a thermopile, which converts the infrared radiation into an electrical signal.
An infrared thermometer processes temperature readings by:
- Directing the object’s emitted infrared light onto a thermopile detector.
- The thermopile converts the infrared radiation into heat.
- The heat is then transformed into electricity.
- The electricity is evaluated as a temperature reading.
Advantages of Infrared Thermometers
Best infrared thermometers classify as non-contact devices because they can measure temperature without requiring physical contact with the object or person being measured. This feature offers a significant advantage, enabling temperature measurement from a distance, making it a device suitable for scenarios where direct contact is not feasible or preferred.

In addition to their non-contact nature, infrared thermometers have a rapid response time, often providing a temperature reading in a fraction of a second. This swift performance enhances their effectiveness in high-volume applications and situations where real-time data is essential. Moreover, their versatility is demonstrated through their capability to store data, deliver rapid and precise temperature readings, and measure temperatures of moving or hard-to-access objects. Their utility spans across diverse applications such as process monitoring, plant maintenance, electrical, HVAC, and automotive maintenance.
Key Features to Consider
It’s vital to keep in mind the features that guarantee accurate and reliable readings when selecting an infrared thermometer. The accuracy of infrared thermometers plays a critical role in their performance. Factors such as the distance-to-spot ratio, emissivity settings, and the thermometer’s temperature range are important contributors to the precision of temperature measurements.
Emissivity is a significant feature as it quantifies an object’s capacity to emit infrared energy, which is crucial for determining its actual temperature itself. Maintaining correct emissivity settings in an infrared thermometer is integral to achieving accurate temperature readings. Additionally, the temperature range of the thermometer should suit your needs. Domestic infrared thermometers generally have a temperature measuring range of –50°C to 500°C, while industrial infrared thermometers typically offer a broader range to accommodate the diverse extreme temperature measurements in industrial environments.

Tips for Accurate Temperature Readings
While infrared thermometers come with numerous benefits, correct usage is key to guarantee accurate temperature readings. Below are some tips for proper application, calibration, and grasp of emissivity.
Proper Usage Techniques
To use an infrared thermometer accurately, you need to consider several factors. One such factor is the understanding of the distance-to-spot ratio, which describes the correlation between the diameter of the area under measurement and the distance from the target. A smaller ratio enables more precise temperature readings by focusing on a smaller area.
The optimal distance for holding an infrared thermometer for precise readings is approximately 6 inches away from the temperature inside the target. To achieve an accurate measurement, it is important to:
- Directly aim the infrared thermometer at the object or body part being measured
- Ensure there are no obstructions between the thermometer and the target
- Hold the infrared thermometer at a 90-degree angle relative to the surface being measured
Following these guidelines will help ensure optimum accuracy.
Calibration and Maintenance
For accurate temperature measurements, calibration of an infrared thermometer at different temperatures is recommended. One commonly used calibration method involves using an ice bath. This entails:
- Filling a large glass with ice and water
- Allowing it to reach thermal equilibrium
- Immersing the thermometer in the water without touching the container
- Calibrating the thermometer to read 32°F (0°C) when pointed at the ice bath.
Regular maintenance is also crucial for optimal performance. Potential consequences of inadequate maintenance include inaccurate readings caused by external factors like dust, smoke, or steam, as well as ambient temperature, humidity, and air currents. Improper calibration can also result in inaccurate temperature readings. It is essential to conduct regular maintenance, including cleaning the lens, inspecting for damage, and ensuring proper calibration, to uphold accuracy.
Understanding Emissivity
Emissivity refers to the efficiency of an object in emitting infrared energy as heat. It is the opposite of reflectivity. In the thermometer’s settings, we must consider an object’s emissivity value, as it impacts the amount of infrared energy it emits, ensuring precise thermal readings.
To adjust the emissivity on infrared thermometers, set the IR sensor’s emissivity value. Match it with the temperature measured by a contact probe. Note, many IR thermometers are pre-set at an emissivity of 0.95. This setting suits most organic objects well. Yet, emissivity values can vary greatly among different materials.
For example, cement has an emissivity value of 0.54, while polished aluminum has a value of 0.05.
Best Thermometer Infrared: Comparing
Infrared thermometers, despite their numerous benefits, may not always be the most suitable tool. We’ll compare them with other types of thermometers, such as contact and probe thermometers, to understand their differences and decide when they could be a more appropriate choice.
Contact Thermometers
Contact thermometers measure temperature through direct contact with the object or surface. They use electronic heat sensors to capture precise temperature data.
Contact thermometers are usually more accurate than infrared thermometers. However, they are more invasive and prone to contamination. They need thorough disinfection after each use. Infrared thermometers, on the other hand, measure temperature without touching. This reduces the risk of contamination.
Probe Thermometers
Probe thermometer is another type of thermometer that utilizes a metal probe to gauge the internal temperature of food or other substances. They are frequently employed in culinary settings to verify that meat reaches the desired level of doneness.
Probe thermometers work by sending an electrical current through a wire in the probe. The wire’s resistance changes as the food’s temperature increases. We measure this change to find out the food’s internal temperature. People use them to make sure food reaches a safe temperature, preventing food-borne illnesses.
Common Misconceptions About Infrared Thermometers
Despite the wealth of information available about infrared thermometers, some misconceptions continue to exist. We’ll tackle some of the most prevalent ones and clarify the facts.
Accuracy Concerns
One of the prevalent misconceptions is that infrared thermometers are inaccurate. In reality, several factors can impact the precision of infrared thermometer readings, such as:
- The angle of measurement
- Ambient temperature
- Air quality
- Electromagnetic interference
- Environmental radiation
- The characteristics of the target
Additionally, factors like emissivity, distance-to-size ratio, and the role of the laser pointer also contribute significantly to determining accuracy.
The distance-to-spot ratio of an infrared thermometer fundamentally determines the diameter of the area being measured relative to the distance from the target. A smaller ratio enables more precise temperature readings by focusing on a smaller area, thereby enhancing accuracy. Nevertheless, external factors such as ambient temperature can influence the accuracy of infrared thermometers, which may result in less precise readings. However, the standard margin of error for an infrared thermometer ranges from 0 to 0.3°C, as determined by various studies and manufacturer specifications.
Limitations in Measuring Internal Temperatures
Another common misconception is that infrared thermometers can measure internal temperatures. However, they are designed to measure surface temperatures only. Additionally, they may need adjustments based on the surface being measured and are less accurate compared to surface probes.
Infrared thermometers can’t measure internal temperatures, like food, liquids, or body temperature. Probe thermometers are better for that, vital in cooking and precise measurements. Knowing these limits ensures you use the right tool.
