Industrial Infrared Thermometer from ThermoWorks. About: “The Industrial Infrared Thermometer is equipped with an 8-point circle laser, which allows you to better approximate your target area without the guesswork of a single laser. This infrared thermometer has an adjustable emissivity feature, which allows you to measure a variety of surface types. For poorly lit areas, the infrared thermometer’s backlit display can be toggled on (or off) for easy reading of surface temperatures.More Info

The Industrial Infrared Thermometer includes a thermocouple socket for use with any type K thermocouple probe. A two line display shows infrared and thermocouple measurements simultaneously. And, with a 30:1 distance-to-spot ratio, the Industrial Infrared Thermometer allows you to measure small target areas from further away (1 inch spot at 30 inch distance). This keeps the lens cool when measuring hot surface temperatures.
The Industrial Infrared Thermometer’s display features include Min/Max, Diff. Mode, Avg. Mode, Hi/Low alarms, and continuous scan mode with a large main temperature display, which reads in °F or °C. It’s everything you need in a professional infrared thermometer.”
Since this is no touch, you can check the temp of yeast washing and yeast rehydration water and your starter wort without the risk of infection. I find mine particularly useful for rehydrating yeast.
Infrared thermometers should not be considered a direct replacement for your standard thermometer. A quality IR thermometer will give you a close approximation of surface temperatures. Note that steam seems to throw off readings. Uses include: Contained yeast rehydration water, chilled wort or starter temperature, kegerator, fermenter or fermenation area and beer tasting samples.
