Surface thermometers can be used to read surface temperature by direct contact or non-contact methods. They can be purchased from various sources and have different temperature ranges. They are useful in the kitchen for food safety and in manufacturing to monitor equipment temperature. Calibration is important for accuracy. Remote displays and easy-to-read displays are important considerations.
A surface thermometer is a device used to read the surface temperature of something. These devices can operate by staying in direct contact with a surface and can also be remote, using non-contact methods to obtain information about temperature readings. They can be purchased through a variety of sources, including kitchen suppliers, scientific equipment catalogs, and suppliers of materials used in manufacturing.
A simple surface thermometer attaches with clips, straps or magnets to the surface of an object. A sensor on the thermometer provides feedback on temperature fluctuations and can send this information to a remote display, depending on the application. Other surface thermometers work by measuring infrared radiation from the surface, often using a laser as a guide. The measurement range may vary, depending on the product; some are tolerant of very high temperatures, while others are designed for applications such as cooking, where the temperature range is relatively limited.
In the kitchen, a surface thermometer can be used to check the temperature of a grill or griddle to ensure it is ready to use and address food safety concerns, in environments where low temperatures could expose people to risk of bacteria from undercooked food. In other contexts, it can be important to monitor the surface of the equipment in a work area, to do everything from processing plate products to the correct temperature to halting production if the equipment gets too hot.
When selecting a surface thermometer model, it is important to note the temperature range, as the device may fail or break if it gets too hot or too cold. Other considerations may include how the device connects and how easy it is to read when it comes to the display. If the thermometer needs to be placed in a hard to reach location, you may need a large display for high visibility or a remote display, which allows people to check temperatures without having to be directly in front of the temperature sensor .
Like other devices used for measurement, a surface thermometer should be calibrated to something of a known temperature if it will be used in an environment where small temperature fluctuations are critical. Devices that require calibration are usually shipped with brief overviews of how to do this, and people can also ship them back to manufacturers for inspection, calibration, and repair if needed. Some companies provide this service free of charge for the lifetime of the device as part of the product warranty.
