Your ultrasonic distance meter is perfect for building-industry professionals who need to know
quickly the measurement or area of a room. The UDM45 can measure distances in a straight
line from 0.5 m to 15 meters (1.7 to 49 ft). Your ultrasonic distance meter transmits ultrasonic
waves to the point you want to measure and then measures the time taken by the waves to
reflect. Afterwards, it calculates and re-transcribes the distance.
