## Long description

The Unit UT345A ultrasonic thickness gauge is a professional-grade instrument engineered for precise, non-destructive material thickness measurements. Utilizing advanced ultrasonic technology, this device allows for accurate assessment of various materials, including metals, plastics, and glass, without compromising the structural integrity of the object being tested. It is an essential tool for industrial maintenance, quality control, and manufacturing environments where monitoring material degradation or wall thickness is critical.
Advantages
This gauge offers exceptional versatility through its wide measurement range and adjustable sound velocity settings, which allow it to be calibrated for a variety of specific materials. The integration of a high-performance microprocessor ensures rapid and reliable data acquisition, while the continuous measurement mode and audible alarm system provide immediate feedback during inspections. Its ergonomic, compact design, combined with a long-lasting rechargeable battery and intuitive interface, ensures that it remains highly portable and easy to use even during extended field operations.
Suitable for
Industrial maintenance and inspection of pipes and tanks
Quality control in manufacturing processes
Detecting corrosion and material thinning in metal structures
Aerospace and shipbuilding component integrity checks
Laboratory and workshop material analysis
When it may not be suitable
This device is not designed for measuring the thickness of non-ultrasonic conductive materials or extremely porous substances that scatter sound waves. It may also provide inaccurate readings if the surface of the material is excessively rough, heavily corroded, or covered in thick, non-adherent coatings that prevent proper acoustic coupling.
Key specifications
Measurement range: 1.00 to 300.00 mm
Sound velocity range: 1000 to 9999 m/s
Display: 2.4-inch LCD screen
Memory capacity: 300 data sets
Power source: 3.7V 2000 mAh Li-ion battery
Operating time: Up to 16 hours
Charging interface: USB-C
Operating temperature: 0°C to 40°C
How to use
To begin, ensure the surface of the material is clean and free of loose debris. Apply a small amount of ultrasonic couplant to the measurement area to ensure optimal sound transmission between the probe and the material. Power on the device, select the appropriate sound velocity for the material being tested, and place the probe firmly against the surface. The device will automatically calibrate and display the thickness reading on the screen. Use the continuous measurement mode for scanning larger areas and utilize the alarm function to flag readings that fall outside of your predefined safety thresholds.
What to consider before purchase
Ensure the material you intend to measure is compatible with ultrasonic testing methods.
Verify that the minimum pipe diameter requirements meet your specific application needs.
Consider the environmental conditions of your workspace to ensure they fall within the operating temperature range.
Check if you have the necessary ultrasonic couplant gel available for your measurements.
Usage recommendations: Always perform a calibration check using a known reference block before starting a series of measurements to ensure maximum accuracy. Keep the probe face clean and free from scratches to maintain signal quality.
