UT345A Ultrasonic Thickness Gauge

The UT345A Ultrasonic Thickness Gauge is a professional industrial measurement instrument designed to measure the thickness of solid materials using ultrasonic technology. Engineers, maintenance technicians, and quality control specialists commonly use this device to inspect metal structures, pipes, tanks, and mechanical components without damaging the material. As a result, the UT345A Ultrasonic Thickness Gauge allows accurate thickness measurement even when access to only one side of the material is available.

Moreover, the UT345A Ultrasonic Thickness Gauge operates by transmitting ultrasonic pulses through a material surface and measuring the time it takes for the sound wave to reflect back from the opposite side. The instrument then calculates the material thickness based on the ultrasonic travel time. Therefore, technicians can measure material thickness quickly and precisely during industrial inspections.

In addition, the device supports thickness measurement across a wide range of materials including steel, aluminum, copper, brass, plastics, glass, and other homogeneous materials. Because ultrasonic measurement works through coatings such as paint or protective layers, the UT345A Ultrasonic Thickness Gauge allows technicians to measure metal thickness without removing surface coatings.

Furthermore, the instrument offers a measurement range from 1.2 mm to 225 mm, depending on the material type and ultrasonic velocity settings. This range makes the device suitable for inspecting pipelines, pressure vessels, ship hulls, storage tanks, and mechanical equipment.

Another important feature of the UT345A Ultrasonic Thickness Gauge is its high measurement resolution and accuracy, which ensures reliable inspection results during industrial maintenance and quality control. The device also allows users to adjust sound velocity settings, enabling accurate thickness measurement across different materials.

The instrument also includes practical functions such as data storage, backlit LCD display, automatic calibration, and automatic power-off. These features help technicians perform inspections efficiently while maintaining battery life during field operations.

Because of its reliable ultrasonic technology and portable design, the UT345A Ultrasonic Thickness Gauge is widely used in industrial equipment inspection, pipeline corrosion monitoring, shipbuilding, mechanical manufacturing, and metal structure maintenance.
