If your alarm limits are exceeded, an audible beep-beep sounds for 5 seconds every minute. During the alarm condition a visual indicator flashes on the screen. If the temperature returns to normal, the visual and audible alarm will stop. The Max/Min function will continue to show you the highest and lowest temperatures reached so you will know that an alarm has occurred.
Everybody needs a couple of these at home. Track daily temperatures in the house or in the garden. Stores the high and low wherever you need it. Put one on your fridge and one on your freezer. You'll save hundreds of dollars in ruined foods. Great for aquariums and greenhouses and much more.
