Ultrasonic Thickness Gauge SR8850

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
