Reed Instruments R7900 Ultrasonic Thickness Gauge (400mm)

High-Capacity Ultrasonic Thickness Measurement for Industrial Use

The Reed Instruments R7900 provides professional-grade thickness gauging for a wide range of industrial materials.6 Utilizing advanced ultrasonic technology, it offers a broad measurement range of 0.75 to 400mm (15.7"), making it a versatile tool for checking material integrity on everything from thin pipes to heavy-duty pressure vessels.

Key Technical Advantages

• Non-Destructive Measurement: Measure thickness quickly and accurately from one side of a part, eliminating the need to cut or damage samples.

• Large Internal Memory: Capture and review up to 500 data points, making it easy to track trends and verify material consistency across large surface areas.

• User-Adjustable Velocity: Easily calibrate the device for different materials by adjusting the sound velocity, ensuring high-accuracy results across different substrates.

• Compact Portability: Engineered for the field, the R7900 is lightweight, easy to calibrate, and features an auto-power-off function to preserve battery life.

Ideal Applications for the REED R7900

• Corrosion Monitoring: Regularly check the wall thickness of pipes, boilers, and pressure vessels to identify thinning and prevent leaks.

• Manufacturing Quality Control: Verify that parts meet engineered thickness specifications in industries like automotive and aerospace.

• Shipbuilding and Marine Inspection: Measure hull thickness and structural integrity without dry-docking or destructive sampling.

• Storage Tank Maintenance: Assess the integrity of fuel and chemical storage tanks to ensure compliance with environmental and safety regulations.

• Infrastructure Safety: Test the thickness of structural steel in bridges and commercial buildings to monitor for long-term wear or environmental degradation.
