REED R7920

This ultrasonic thickness gauge is a portable device used for non-destructive measurement of the thickness of metal and other materials. It uses high-frequency sound waves to determine the thickness of a material by measuring the time it takes for the sound waves to travel from the gauge to the material and back. The R7920 features user-adjustable high/low alarms, internal memory capable of storing up to 300 measurements, and a simple user interface, making it suitable for use by technicians and inspectors in a variety of industries.
