ULTRASONIC THICKNESS GAUGE GT1201
The GT1201 ultrasonic thickness gauge is a modern measuring device designed for fast, non-destructive measurement of material thickness and the speed of sound wave propagation. The built-in microprocessor ensures stable operation, high accuracy, and convenient use.

The instrument is used in manufacturing, maintenance, quality control, and technical inspections. It is ideal for assessing the condition of pipelines, pressure vessels, structural elements, and other components where access to the opposite side of the material is not possible.

The gauge enables measurement of materials that transmit ultrasonic waves at a constant speed and provide a clear reflection from the back surface.

APPLICATIONS
The device allows thickness measurement of materials with parallel surfaces that transmit ultrasonic waves well, such as:

metal, aluminium, copper, glass, ceramics, plastics, resins, water, glycerin, and other materials with similar properties.

Measurement is not recommended for cast iron due to its grainy structure.
