This is one of the nicer digital thermometers we have used recently. It has a range of -40° to 350°F (-40° to 175°C). The stainless steel stem features Quick Tip technology, which means that this thermometer reads the correct temperature within 8 seconds or less. It is waterproof, which makes it ideal for brewing applications. This thermometer is incredibly easy to calibrate — just place the probe in at least 1 inch of crushed ice and water and press the "Calibrate" button for two seconds. The ProAccurate Digital Thermometer also has a min/max function, and shuts off after 10 minutes of non-use. It is warrenteed by the manufacturer for five years.
