Industry's first economical digital thickness gaugeThe zero measurement technology,high resolution, A scanning snapshot function is based on ful digital technology. The UM-4D now offers Through-Coating Thickness Measuring Capability |
|
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 technologyBased 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.
