Ultrasonic Thickness Gauge GM100
The GM100 Ultrasonic Thickness Gauge is a professional-grade, handheld non-destructive testing (NDT) instrument designed for fast, accurate thickness measurements across a broad range of industrial materials. Leveraging ultrasonic pulse-echo technology and microprocessor control, the GM100 enables reliable assessment of material thickness without requiring access to both sides of the workpiece, making it ideal for field inspections, maintenance, quality control, and production monitoring

Important Notes
-
The GM100 performs non-destructive thickness measurement and requires access to only one side of the test object.
-
Correct sound velocity selection according to material type is essential for accurate measurements.
-
Use of ultrasonic couplant is recommended to ensure proper probe contact and reliable readings.
