What is an infrared thermometer?
Infrared thermometer is a type of thermometer that allows to measure temperature without touching people or objects , measuring based on the principle of measuring the amount of infrared emitted by the body. Infrared thermometers can measure forehead, ear or have built-in forehead and ear thermometers.
Infrared thermometer construction
- The sensor part is responsible for receiving the body’s wavelength.
- The LCD screen is located on the thermometer body to display the measured results on the body temperature.
- Adjustment buttons such as power off and on, convert measurement units and can switch from measuring human body temperature to measuring room temperature.
Working principle
Any object with a temperature above -273 degrees Celsius emits thermal radiation or infrared waves and so does the human body. The infrared sensor will measure the level of energy emitted by the object we want to measure, then calculate and display the result on the LCD screen.
Uses of infrared thermometers
Infrared thermometers are widely used in practice, with diverse uses in many different fields, especially popular in the medical field to measure body temperature.
In addition, infrared thermometers can also measure the ambient temperature , helping you know the temperature of the surrounding space.
Many applications in industry : measuring the temperature of engines, machinery, furnaces, measuring temperature from a distance, in places where it is difficult to contact, many toxic substances. This type of thermometer is trusted by engineers because of its accuracy and fast measurement speed.
Besides, the infrared thermometer can measure the surface of objects , you can use it to measure the temperature of water, milk, dishes, …

In addition to the above popular infrared thermometer brands, there are also quite good quality brands such as Braun, Laica, Polygreen infrared thermometers, etc. You can also find yourself a good infrared thermometer suitable for these products of these brands.
Criteria to know when choosing to buy an infrared thermometer
Error
The accuracy of the thermometer is a very important criterion. However, current infrared thermometers all have certain errors. The error of infrared thermometer from ± 0.2 – 0.3 degrees Celsius is standard.
How to use a thermometer?
How to use an infrared thermometer is very simple, press the button to start the thermometer, let the temperature probe be 1 – 3cm away from the measurement location (forehead, armpit, neck). Then, hold the START button for 1 – 3 seconds and when the transmitter beeps, the measurement is completed.
You can read the results on the thermometer display in just 5 seconds .
Included Utilities
The infrared thermometer is conveniently designed, has a compact handle that is convenient to hold while measuring, a sharp LED screen, a clear number display for you to easily observe.
The thermometer is equipped with a warning feature when the body temperature is above 37.5 degrees Celsius , the thermometer will sound 10 continuous beeps and display red on the screen.
Measure
Infrared thermometer can measure Celsius and Fahrenheit with high accuracy. You can easily choose the unit of measurement that suits your needs.
Response time
The fast response time is an outstanding advantage of infrared thermometers over other thermometers. Infrared thermometer responds to measurement results within 2 – 5 seconds .
Memory storage
Memory capacity is also a criterion you need to consider when choosing to buy an infrared thermometer. The thermometer can store the number of measurements from 25 to 50 times , helping you to monitor the disease condition easily.
Reputable place to buy
Infrared thermometer is a device used for health care, so you should choose to buy a thermometer at a reputable sales place to avoid buying fake and poor quality goods.

In conclusion, an infrared thermometer is a non-contact temperature measuring device that uses infrared technology to detect thermal radiation emitted by an object or surface. This technology allows for quick and accurate temperature readings without the need for physical contact, making it a convenient and hygienic option in various applications.
The uses of infrared thermometers are extensive and diverse. They find applications in various industries such as automotive, manufacturing, food processing, HVAC, and medical. They are commonly used to measure surface temperatures of objects, liquids, and even human body temperatures. Infrared thermometers are particularly useful in situations where contact thermometers are impractical, difficult to use, or present a risk of cross-contamination.
When considering purchasing an infrared thermometer, several criteria should be taken into account. One key consideration is the temperature range or measurement range that the device can cover. It is important to select a thermometer that can cater to the specific temperature requirements of the intended application.
Additionally, the accuracy and repeatability of temperature readings are crucial factors. Look for infrared thermometers with a high degree of accuracy and consistency in measurements, as these aspects greatly affect the reliability of the obtained results.
Another important criterion is the distance-to-spot ratio, also known as the optics, which determines the area of the target that is measured at a particular distance. A higher ratio implies a smaller area being measured, providing a more precise temperature reading.
Other factors to consider include the response time, display features, durability, ease of use, and any additional functionalities or features that may be required for specific applications.
In conclusion, with their contactless and efficient measurement capabilities, infrared thermometers have become essential instruments across a wide range of industries. Selecting the right infrared thermometer involves a careful evaluation of the temperature range, accuracy, optics, and other important criteria to ensure optimal performance and reliability in various applications.
