UT 25 in Uzbekistan, Tashkent

Works with a variety of dual-coupler converters from 2.5 MHz to 10 MHz, providing highly reliable results in the laboratory, shop, and field.

The device is implemented on a modern electronic base, equipped with a bright color screen and built-in memory for storing settings, characteristics and results. It has a simple and intuitive interface.

One of the advantages of the device is that it works with specialized high-temperature sensors, which allow one-way monitoring of parts with surface temperatures up to 350°C. Objects of control can be metal pipes or tanks without taking them out of service, various steam pipelines, metal rods and castings before they are cooled.

Simple and quick calibration allows you to set up the thickness gauge within 10 seconds. The device can be calibrated either against a reference sample or against a known thickness on any material.

The lightweight and convenient shock-resistant case provides dust and moisture protection in various operating conditions, and resistance to falls from a height of up to 2 meters.

The device is used for rapid measurement of the thickness of metal and non-metal products (sheets, containers, pipes, pipelines, bridges, hulls, transport and other structures), during operation to determine their corrosion state or after manufacture.

It is used in energy, metallurgical, mechanical engineering, shipbuilding, transport and other industrial enterprises.
