When deciding whether you need an infrared thermometer for your home, you may wonder what the difference is between one type of thermometer and another. Essentially, the infrared thermometer measures the amount of thermal radiation, also known as black-body radiation. This radiation has a specific wavelength and is directly proportional to the temperature of the surface. As a result, it makes it an excellent tool for many uses, from monitoring the temperature of food to measuring the heat in a room.

Non-contact measurement

This thermometer is entirely safe for the patient, as the device is not in contact with the subject’s surface. The measurement is also very accurate. However, not all materials give off thermal radiation the same way, so non-contact measurement requires careful consideration. Non-contact thermometers can be classified based on emissivity, measured on a scale from 0.00 to one.

NCITs are also becoming widely used in the COVID-19 pandemic, which is characterised by temperatures higher than 38 degC. Accurate temperature measurements are vital for successful screening. However, this method requires that the measurement be done at least six feet from the affected person. In avoiding contamination, the temperature should be at least six feet away. Non-contact measurements with infrared thermometers are widely used in clinical settings.


Infrared thermometers have many applications. For example, they are often used to measure the temperature of corn, water, and other materials. They can also monitor the temperature of a baseball strike or an entire battlefield. The applications of infrared thermometers are nearly limitless. They can be used for various purposes, including medical care, aerospace, and engineering. The following are just a few of these applications.

Infrared thermometer can be portable or fixed. Non-contact models have a lens that concentrates the thermal radiation of an object. A detector then converts the radiant power into a measurable electrical signal. Infrared thermometers are great for measuring temperature from a distance because they do not require the object to contact the device directly. This type of thermometer is best for situations where a thermocouple is impossible or inaccessible. These thermometers provide accurate data and can be used in various applications.


The accuracy of infrared thermometers depends on their distance to the target. The distance should be equal to or larger than the spot size, and the latter will decrease the accuracy of the reading. If the distance is small, the target diameter will be smaller—however, the further the distance, the larger the target diameter. Therefore, to maximise accuracy, a larger target diameter should be chosen. The distance between the target and the thermometer should be 12 feet.

Infrared thermometers use an electronic component to measure the temperature of an object or living body. The electrical signal is then amplified, linearised, and stabilised before being sent to the display unit. The display unit then displays the temperature value on a Celsius or Fahrenheit scale. The infrared thermometer is often connected to a trigger button that emits a beep when the temperature changes.


The distance between the food and the device should be considered when buying instrumentchoice.com.au infrared thermometer. The distance between the device and the food will influence the accuracy of the readings. Infrared thermometers have a wide range of emissivity and distance from the surface. An ideal one will measure food at an average distance of 12 inches. Then, the device will indicate whether the food is done or not.


The global infrared thermometer market is competitive, with each manufacturer striving to maintain a higher level of profitability. Moreso, with the growing awareness of the importance of infrared thermometers, more companies are implementing different strategies to increase margins. For example, major players are increasingly pursuing mergers and acquisitions, joint ventures, and strategic partnerships to improve their market position. In addition, many manufacturers offer volumetric discounts by bundling multiple products in one bundle.


An infrared thermometer produces a variation in temperature based on the emissivity of the material it is attached to. This value varies from 0.00 to just under 1.00. Reflective and shiny surfaces have lower emissivity than other materials. If you do not know how to adjust the emissivity of your infrared thermometer, it can give you an inaccurate temperature reading.
