Product Description
Digital Ultrasonic Thickness Gauge Sound Velocity Meter Metal Depth tester 1.2-225mm Smart Sensor AS840 with LCD display
Digital Ultrasonic Thickness Gauge Sound Velocity Meter Metal Depth tester 1.2-225mm Smart Sensor AS840 with LCD displaySMART SENSOR Ultrasonic Thickness Gauge This unit is an intelligent handheld product, which adopts ultrasonic measuring principle, and is controlled by micro processor, provides quick and precise measurement of thickness for most of industrial material. This unit is widely
used in various precise measurement for different hardware / parts in industrial realm; one of its important application is to monitor the level of thickness-decreasing during operation of various and pressure container. Diffusely
applied in manufacture fields, metal processing, and commercial inspection.
Scope of application
This unit is suitable for measuring materials that are good ultrasonic conductor such as metal, plastic, ceramic, glass etc.,as long as the measured part in two parallel surfaces for measurement of thickness. This unit is not suitable for cast iron
due to its big crystalloid composition.
1. Auto calibration to assure the accuracy.
2. Auto linear compensation: this advanced software program enhances the precision by correcting the non-linear accuracy of transducer.
3. Use and keys to make a quick adjustment for the sound velocity /thickness,and a quick recall to the stored data.
4. Coupling status indication: Observing the coupling icon to learn if the coupling is accomplished or not.
5. 10 thickness measurement storage and recall function is available,
6. which facilitates the height work or working in wild area.
7. 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.
8. 12 sound velocity for different material
9. Low battery indication
10. Auto power off mode designed to conserve battery power.
11. More than 10000 times long lift keys.
12. Manual power off
