Taylor 5327 Thermometer, Analog, -40 to 100 deg F, Plastic Casing

An accurate outdoor temperature reading without leaving the warmth of your own home. With the TAYLOR indoor and outdoor thermometer, see current indoor and outdoor temperatures ranging from -40 to 100 deg and -40 to 40 deg C. While the thermometer's red meter shows your inside temperature, the blue meter shows the temperature outdoors. Simply mount the thermometer indoors and extend the 45 long copper tubing out of a nearby window.
