DecentGadget Ultrasonic Thickness Meter Tester Gauge Velocity 1.2~225mm Metal Wave;

Features:
-Auto Calibration to assure the accuracy
-Auto linear compensation: this advanced
-Coupling status indication: Observing the coupling icon to learn if the coupling is accomplished or not
-10 thickness measurement storage and recall function available, which facilitated the height work or working in wild area
-Sound velocity measurement: with a given thickness by a sample hardware to measure the sound velocity, which avoid the further conversion or consultation of the table
-12 sound velocity for different material which also adjustable
-More than 10000 times long life keys
-The unit has a special memory that retains all of its setting even when the power is off
