Features
•Auto calibration to assure the accuracy
•Auto linear compensation with advanced software program that enhances the precision by correcting the
non linear accuracy of transducer
•Usage of keypad for a quick adjustment for the sound velocity thickness and a quick recall to the stored data
•Coupling status indication
-Coupling icon displays if the coupling is accomplished or not. 10 thickness measurement storage and recall
function is available which facilitates the height work or working in abnormal area
•Sound velocity measurement
-Given thickness by a sample block to measure the sound velocity thus avoiding further calculation or consult table for sound velocity of different materials.
•Low battery indication
•Auto power off mode designed to conserve battery power
•More power off mode designed to conserve battery power
•Long life keypad for more than 10000 times key presses.
