Features

• Auto Calibration to assure the accuracy
• Auto linear compensation: this advanced software program enhances the precision by correcting the non-linear accuracy of transducer
• Use up and down keys to make a quick adjustment for the sound velocity/thickness and a quick recall to the stored data
• 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
• Low battery indication
• Auto power off mode designed to conserve battery life
• 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
