Ultrasonic Distance Measurer

Distance Measurer can measure distance from 2 ft to 60 ft away. Requires one 9V battery (not supplied). It is sensitive to changes in temperature and humidity. For accurate measurements, be sure there is a clear path between you and the points that you are measuring. Can measure in feet or meter. Not just a distance measure - can also measure the area or volume of a room and temperature in Cº or Fº. You can "store" measurement using the store key and one of the 3 memory keys. 6.1" L x 2.8" W x 1.9" H
