A Quick Guide To Infrared Thermometers

May 13/2023 HVAC &R

Infrared (IR) thermometers are useful instruments for measuring temperature accurately and consistently in a variety of settings. They are utilised in a wide range of sectors where accurate and effective temperature measurements are necessary. You should be aware that these are industrial tools and not thermometers used in medicine.

What is an infrared thermometer?

The most accurate, secure, and reliable infrared thermometers are from Testo. These thermometers employ infrared technology to quickly and non-contactly assess surface temperature and, in some circumstances, interior temperature. Pyrometers, commonly referred to as laser pointer thermometers or infrared thermometers, are trusted tools for measuring temperature in addition to conventional thermometers.
Because environmental control is crucial to quality control, reliable infrared thermometers are beneficial to a wide range of businesses. The following are some of the numerous trades and professions that depend on precise measurement:

  • HVAC
  • Electrical
  • Processing plants
  • Food production, food service and retail
  • Other industrial areas

You may perform effective and essential temperature measurements with the help of industrial infrared thermometers, including accurate measuring area readings for reflecting surfaces. You will be well-prepared thanks to the non-contact IR thermometer, particularly for collecting control measurements in business and industry.

Applications of an infrared thermometer

A thermometer that emits infrared light has several industrial uses. The advantages of a non-contact infrared thermometer can provide an accurate reading of the surface’s or a selected location’s temperature. In order to assure safety, consistency and accuracy are crucial in various uses.

Because the temperature may be measured remotely, non-contact thermometers are perfect for machinery and moving targets. Additionally, dangerous or inaccessible targets are used with laser pointer thermometers. Keeping track of these precise measures not only adds a layer of quality control but also shields the business from potential legal action.


To operate efficiently, many different industries depend on their machinery and equipment to be in top shape. Hot areas are frequently a sign of possible problems in that piece of equipment. For precisely this reason, temperature audits are carried out. Since an expert can evaluate the problems and maybe replace or solve the looming issue, they can stop the equipment from entirely breaking down.

Building and storage temperatures

Building and warehouse managers can use infrared thermometers to check the storage temperature is precise and safe for the goods or to discover insulation leaks using surface temperature variations. By addressing environmental concerns, the manufacturer may be able to save money. An accurate reading is required because some materials have specified temperature requirements and should be handled at those temperatures with minimal to no variation. An sensor for detecting infrared temperatures can aid in preserving this.

Food temperatures and incoming goods check

Certain foods must be transported, stored, and served at a specific temperature for safety reasons. In addition to their reputation being on the line, caterers, grocers, and other food enterprises who fail to do this risk breaking food safety laws.

Mould detection

Both the testo Smart Probes App and the testo 805i infrared non-contact thermometer are practical professional instruments for spotting potential mould. The humidity and room temperature are important indicators of the presence of mould in a building or environment.

How do I read an infrared thermometer gun?

Despite the ease of use of testo thermometers, typical errors still occur. Knowing how to utilise them is crucial for getting the most accurate readings. Some of the most crucial advice is provided below:

  • Ensure that the lens is clean.
  • Try to make sure that the surface is relatively dirt free.
  • Get as close as you can to the target.
  • Calibrate the tool.
  • Ensure you have the correct emissivity setting.
