In recent years, the expansion of applications for FRP, rubber, and special resins has been remarkable, and along with this, the necessity for measurement inspection and quality control and assurance of materials and products through non-destructive testing is increasingly demanded. The UDM-1100 is a pocket-type ultrasonic thickness gauge developed to meet these needs, specifically for resins. It does not have data recording functionality. The UDM-1100 reliably measures thickness from the surface to the back even in the presence of noise echoes reflected from the laminated parts, such as those found in FRP, through the use of a special probe and signal processing. It is ideal for measuring the thickness of FRP hulls, aircraft, storage tanks, septic tanks, synthetic resin products, and rubber products. For more details, please contact us.
