Working Principle

The principle of ultrasonic thickness measurement and light wave measurement principle is similar. Probe fired ultrasound Wave pulse reaches the measured object and spread in the object, when the material interface is reflected back The probe determines the material under test by precisely measuring how long the ultrasonic wave travels in the material thickness.


●  Can be equipped with a variety of different frequency, chip size, double crystal probe use.

●  Have probe zero calibration, a two-point calibration function, can be automatically on system error correction.

●  Thickness can be known the sound velocity measurement, in order to improve the accuracy of measurement.

●  With functions of coupling status alerts.

●  LED backlight display, convenient to use in dark environment.

●  The battery indicator function, can real-time display the battery remaining power.

●  With automatic power saving function dormancy, automatic shutdown, etc.

●  Small, portable, high reliability, suitable for bad operating environment, vibration, impact resistance and electromagnetic interference.
