Digital Aquarium Temperature Alert

A unique digital device that provides accurate measurement of your aquarium water temperature. When the temperature falls below 75 degrees or rises above 82 degrees Fahrenheit, a built in alarm beeps and flashes. (This feature can be turned off.) Includes a built-in clock that displays AM/PM or 24-hour time. Also records the highest and lowest temperatures recorded since the previous clearing of the unit's memory.

Three foot cord with all-plastic probe and suction cup. To use, simply submerge the probe with suction cup. Then, attach the digital unit to the outside of the aquarium using the double-stick tape that is provided. Includes two button cell batteries. Measures approximately 2-2/3 "x 1-2/3". For fresh or saltwater use.
