The DT101 also has a LOW and HIGH memory. The memory will display the Lowest and the Highest temperatures that the unit has been exposed to, since it was last reset. The memory may be reset at any time.
This thermometer operates on one common 1.5 Volt AA cell battery (included). The battery will power the thermometer continously for over 5 years!
The sensor is mounted directly on top of the unit, where it may be conveniently used, or it may be extended (on its flexable cable) up to 3 feet away, to allow it to be inserted through a window or door for outside temperature reading while you are inside the house.
While not technically a "Frost Alarm", this simple versatile thermometer has found wide spread use in agriculture.
