By combining a main unit that displays the indoor temperature and the temperature from a remote, wireless sensor that can be set up either indoors or outdoors up to 100 feet away, this battery-operated, radio-wave set monitors conditions at two locations simultaneously. (The main unit will handle up to two additional remote, wireless sensors, though those must be ordered separately.) The large LCD display shows the temperature at the main unit's location on the left and the temperature at the remote sensor's location on the right. Minimum/maximum temperatures recorded for any given period can be recalled, and the measuring period can be reset at any time. The display can be set for either Fahrenheit or Celsius. The remote sensor also has been preprogrammed to sound an alarm when the temperature at its location falls to 38 degrees F--ideal for, say, a garden or garage. The main unit uses two AAA batteries and the remote sensor one 9V battery (batteries not included). The main unit comes with a desktop stand or can be hung by a nail or screw with a wall-mount slot in the back. It measures 5 inches wide, 3 inches high, and 7/8 inch deep. The remote sensor has a built-in desktop stand or can be wall mounted and measures 2-3/8 inches wide, 3-1/2 inches high, and 1 inch thick. Because no assembly is required, the system operates as soon as batteries are installed.
