Mini Ultrasonic Digital Tape Measure
Mini Ultrasonic Digital Tape Measure is a perfect tool to quickly know the distance, area and volume of a room! It can measure distances in a straight-line from 0.5m to 18m. Your distance measurer transmits ultrasonic waves to a point you want to measure.
Afterwards, it measures the time taken by the waves to reflect and then calculates and re-transcribes the distance.
