Infrared thermometers
The UL Advantage
In recent years, infrared thermometer technology has been refined and improved. Now relatively low-cost, hand-held devices can deliver much more accurate temperature measurements over a greater temperature range. This has enabled the use of infrared thermometers for food-safety applications as a screening tool.
It is important to use the right tool for the job. UL offers an infrared thermometer certification service that helps food safety professionals to choose an infrared thermometer that produces accurate surface temperature measurements under a variety of expected use conditions. Manufacturers must also inform the user on the proper use and limitations of the device.
There are a number of resources that may be helpful:
- Now online, read the Guide to Use Infrared Thermometers for Measuring Surface Temperatures that helps the food service professional screen critical temperatures in food applications (requires Adobe Acrobat)
- Order a copy of ANSI/UL 2333
- Query the UL directory of Listed infrared thermometers
