Ultrasonic Thickness Gage (Basic Type) – Simple, Reliable Wall Thickness Measurement
An Ultrasonic Thickness Gage (Basic Type) is a non-destructive testing (NDT) instrument designed to measure the wall thickness of materials from one side using high-frequency ultrasonic waves. This basic type model offers essential measurement capabilities with straightforward operation, making it ideal for routine inspection tasks in industrial and maintenance environments.
By emitting ultrasonic pulses and measuring their echo time, the gage accurately determines the thickness of metals, plastics, glass, composites, and other homogeneous materials—even through coatings or corrosion, depending on model support. Compact, portable, and user-friendly, it is widely used where destructive testing is not feasible and consistent material thickness is crucial for structural integrity.

How to Use an Ultrasonic Thickness Gage (Basic Type)
- Surface Preparation: Clean the area to be tested; remove rust, paint, or debris for better coupling.
- Apply Couplant: Use a gel or liquid couplant between the probe and test surface to transmit ultrasound effectively.
- Power On and Calibrate: Turn on the unit and calibrate it using a reference block of known thickness.
- Position the Probe: Place the probe firmly on the test surface.
- Read the Display: Thickness appears instantly on the digital screen.
- Repeat & Record: Take multiple readings for consistency and note down the lowest value if corrosion is suspected.
