The La Crosse Wireless Thermometer is an elegant, inexpensive way to keep track of indoor and outdoor temperatures, including trend data and minimum/maximum records. It's perfect for those who have no need for more advanced weather stats like humidity and barometric pressure, and, accordingly, don't want to pay for features they'll never use. Completely wireless, an included remote sensor gauges outside temperatures and transmits readings up to 300' to the digital thermometer, eliminating the need for cumbersome, bulky wires. A built-in sensor measures indoor temperature, and the compact unit displays both figures on an easy-to-read display. A manually set digital clock is also included on the 2 5/8" long x 1 3/8" wide x 3 11/16" high display. Both the remote sensor and main unit are powered by two AA batteries (not included). With its sleek, stylish design, the Wireless Thermometer looks fantastic anywhere - kitchen, bedroom, office, bathroom - the list goes on. Why wrestle with hard-to-read mercury thermometers and complicated phone and computer apps, when La Crosse provides such an attractive, user friendly solution in its innovative Wireless Thermometer? Don't forget friends and family! The Wireless Thermometer makes an excellent gift!
