Reed Instruments R7900 Ultrasonic Thickness Gauge with NIST

Precision Non-Destructive Testing with Certified NIST Accuracy

The Reed Instruments R7900-NIST is a high-performance ultrasonic thickness gauge designed to measure the wall thickness of various materials from 0.03 to 15.7" (0.75 to 400mm) without damaging the surface. Ideal for industrial applications requiring strict compliance, this model includes a Traceable Calibration Certificate to satisfy safety audits and quality assurance protocols.

Key Technical Advantages

• Versatile Material Measurement: Accurately measure steel, cast iron, glass, and plastics using the adjustable sound velocity range (1000 to 9999m/s).

• Advanced Data Management: Store up to 500 readings in the internal memory, allowing for extensive field inspections without stopping to record data manually.

• Intelligent Display: The backlit LCD ensures clear readings in low-light environments, displaying results in both inches and millimeters.

• Durable & Reliable: Built to withstand industrial environments, featuring a 5MHz transducer and a fast-response standard mode for efficient workflow.

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.
