2. Main functions
● With both metric and imperial display
● Automatic calibration zero, the system error can be amended
● Linear automatic compensation, in the whole range of the use of computer software to probe the nonlinear error correction to improve accuracy.
● The upper and lower adjustment keys can be used for quick adjustment of the speed of sound and thickness.
● Coupling status indication: The coupling flag is provided, and by observing the steady state, the coupling is normal.
● can store ten thickness values, the data is not lost after shutdown, for the high-altitude and field work convenience.
● Measuring speed of sound function: according to sample thickness directly measure the speed of sound, to avoid the trouble of look-up table or conversion.
● can store five different materials, the speed of sound.
● Low voltage indication.
● automatic shutdown: regular automatic shutdown will help you to power.
● full-membrane membrane closed operation ---- anti-oil, improve service life.
