REED R7920 Offers
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.
Features
- Measures the thickness of steel, cast iron, aluminum, acrylic resin, red copper, brass, zinc, quartz glass, polyethylene, PVC, grey cast iron, and nodular cast iron
- Easy-to-read backlit LCD display
- User-selectable units of measure (in/mm)
- Internal memory stores up to 300 measurements
- Displays sound velocity at the touch of a button
- User-adjustable High/Low alarms
- Automatic material calibration
- Auto shut-off and low battery indicator
