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.
