About their lineup, from ThermoWorks: “Easily measure surface temperatures with ThermoWorks non-contact IR guns, ideal for produce and agriculture inspectors, HVAC, construction, warehouse, quality assurance, HACCP and cold chain management, both shipping and receiving. Choose from fixed or adjustable emissivity, single, dual or circle laser types, and lens optics from close focus—for electronic components and laboratory measurements—to 100 to 1—for long distance measurements. High temperature ranges up to 3272°F (1800°C) are perfect for metallurgy and metal work foundries.”
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 a conventional 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 fermentation area and beer tasting samples.
