Hand-Held Digital Ultrasonic thickness gage with 3.5″” Sunlight Readable Color Display for thickness only including: Echo to Echo Software, Plastic Carrying Case, 2 Oz. bottle of couplant (C-02G), Re-Chargeable Li-Ion batteries, DKS537, 5MHz, .375″” diameter Transducer with potted cable, Charger adapter with USB cable and data xl interface program.


Includes all the features of the ECHO 9 plus a live color waveform (A-scan). (No Datalogger) with the live waveform, you can adjust range, gain, blanks and rectification. ECHO 9W also includes the ability to display the thickness of the coating and the substrate thicknesses at the same time as well as the ability to calibrate on their individual sound velocities.

Includes all the features of the ECHO 9 plus “unlimited” reading Datalogger with export to Excel, B-scan (2 GB removable micro SD card standard, other Micro SD cards up to 32GB are optional). Data XL interface program to export saved readings to p.c. (excel).

The ECHO 9DLW comes with everything included in the other ECHO 9 Series thickness gage models including live color waveform, “unlimited” thickness readings via internal Datalogger with removable micro SD card including: plastic carrying case (PC-09), 2 Oz. bottle of couplant (C-02G), rechargeable LiIon battery, DKS537, 5MHz, .375″” diameter Transducer with potted cable, Echo to Echo, and B-Scan, a custom rubber boot with padded wrist strap, charger adapter with USB cable and Data XL interface program to export saved readings to p.c. (excel). The ECHO 9DLW also includes the ability to display the thickness of the coating and the substrate thicknesses at the same time as well as the ability to calibrate on their individual sound velocities.
