    From Active Air the maker of our Hygro-Thermometer with a larger display screen. This version of the Hygro-Thermometer's has similar features in a smaller unit but also provides an alarm clock option. Prop it up on your workspace, close to your plants, or wall-mount it for hands-free readings.

    The Active Air Hygro-Thermometer can stand on a surface or mount on an indoor wall with a screw. To read the outdoor temperature you can locate the 9 foot wired sensor probe outdoors by pushing the tiny probe through a window or small hole in the wall.
