NM01AMZUM2D

The YUSHI UM-2D Digital Through Coating Ultrasonic Thickness Gauge is a portable instrument designed for accurately measuring the thickness of materials, particularly metals like steel, without the need to remove surface coatings such as paint or protective layers. This is achieved through its "Echo-Echo" (E-E) mode.  

This gauge, manufactured by YUSHI, is capable of measuring material thickness ranging from 0.8mm to 300mm (in steel). This wide measurement range makes it suitable for a diverse array of applications across various industries. The gauge offers selectable resolution, allowing users to choose between 0.01mm (high resolution) for precise measurements of thinner materials and 0.1mm (standard resolution) for general applications and thicker materials.  

A key feature of the YUSHI UM-2D is its Echo-Echo (E-E) mode, also known as "Through Coating" measurement. In this mode, the gauge analyzes multiple back-wall echoes of the ultrasonic signal, effectively ignoring the thickness of the coating layer. This is crucial for inspecting coated materials where removing the coating would be time-consuming, costly, or potentially damaging. By measuring the time difference between two successive back-wall echoes within the base material, the UM-2D accurately determines the substrate thickness.  

The YUSHI UM-2D is designed to be user-friendly, typically featuring a clear digital display and intuitive controls for setting parameters such as material velocity, measurement units, and resolution. It is likely powered by batteries for portability and field use.
