As of this posting and for a limited time, Thermoworks has discounted a good selection of infrared thermometers as part of an open box sale. Prices start at just $23. Note that you must use the private open box sale page to get these deals. Check ThermoWorks for current selection, prices and availability.
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. If you’re looking for a great conventional thermometer consider Thermapen ONE – Hands on Review
