UM-4 Series A/b-Scan Ultrasonic Thickness Gauges is used for measuring the thickness of metal materials, pipes, pressure vessels, sheet metals (steel, aluminum), plastic, steel pipes, PVC pipes, glass and other materials. Also be widely used in manufacturing, metal processing industry, chemical industry, industry inspection and testing field.
2.4 Color OLED, 320×240 Pixels Display, A-Scan Snapshot, Echo-Echo Mode(Thru Paint & Coatings), Stores 100,000 Measurement Values, etc.
3.Main functions of UM-4DL
the only product using clear bright color OLED in the same product class.
Contrast:10000:1 40 times than TFT color LCD screen
Resolution320×240,9 times than the same product class
Faster measurement update rate
4Hz for ordinary use,higher update rate can be chosed when need a quick scan.
The innovative A scanning snapshot function Marks the economical thickness gauge into digital age.
UM-4DL first provides A snapshot scanning waveform display function in the same product class.Ultrasonic is no longer an abstract concepts.Users can see directly on the screen of ultrasonic signal,to verify the thickness reading is correct, analyze the cause of the problem and help the user to find the solution to the problem.
Industry's first economical digital thickness gauge
The zero measurement technology, high resolution, A scanning snapshot function is based on full digital technology.
The UM-4D now offers Through-Coating Thickness Measuring Capability
-You can now test painted tanks, pipes, etc., without needing to remove the paint or make corrections for the paint thickness. 1.no need of zero calibration 2.Measured value is not affected by coupling probe pressure, layer thickness and the influence of the surface dirt stains 3.zero drift
More memory, more convenient storage capability
Store 100000 thickness value, is 20 to 200 times of class products;domestic first grid type of storage files display 15 thickness value per screen,According to its position in the grid, making it easy for users to browse the thickness data ,USB 2.0 (Full Speed) ,Powerful DataView data statistics and management software
The only real 0.01 mm resolution of ultrasonicthickness meter in the same product class.
Ultrasonic thickness gauge display resolution is usually 0.01 mm, but it's hard for the real resolution up to 0.01 mm.Ordinary Timing counter within the thickness gauge is generally below 30 MHZ,With the breakthrough full digital technology and special algorithm, The true resolution of UM-4 can reach 0.01 mm, Lots of experiments prove that it's easy for UM-4 to distinguish that thickness is only 0.01mm of two blocks.
Adopted the zero measurement technology
Based on full digital technology,with the zero measurement technology,the measured value will not be affected by echo intensity,material attenuation coefficient,the gain and the height of the gate,so the result has high stability and reliability.
More practical function
