All-in-One Kit Contact 2 Ultrasonic Pulse Velocity Tester

Ultrasonic Concrete Tester

All-in One System is modular Ultrasonic pulse velocity test equipment kit for Non-destructive testing of checking homogeneity of concrete structures, masonary & rocks. The NDT instrument is designed for construction, building and geophysical research industry.

All-in One system serves the function of ideal field use instrument that is  :

- rugged and reliable Ultrasonic test equipment .
- with various dedicated piezoelectric sensors and probes 
- with a multichannel controller and 
- selectable sampling rates from 1OOHz – 10 MHz 
- All acquired signals are displayed, computed and memorized directly on tablet pre-installed software. Connection between All-in One system and tablet is via Wi-Fi. 

 All-in-One, manufactured by Solgeo Italy is available in two Kit options  for Ultrasonic and sonic testing :



# of transducers used


Contact KIT 2

Ultrasonic Pulse Velocity test measurement Kit

1 transmitter, 1 receiver


Contact KIT 3

Ultrasonic and Sonic test measurement Kit

Note: All-in-One is further scaleable, per user requirement for Cross Hole testing.

All-in-One Contact KIT 2: Ultrasonic Pulse Velocity test equipment is based on use of based on 2 nos 55 kHz or 20 kHz transducers for evaluating concrete homogeneity uniformity, cavities, cracks, delamination & deterioration for determining quality of concrete and other masonry materials of structures. Conforms to UNI EN 12504-4 ASTM D2845-08 and ASTM C597-02 standards

 KIT CONTACT 2: Ultrasonic Pulse Velocity Test KIT comprises of:

  • CONTACT-APP software for data storage
  • 2 nos transducers including 1 nos Ultrasonic transmitter T x 55 kHz with 5m cable length and 1nos Ultrasonic receiver R x 55 kHz with 5m cable length
  • Test sample, transport bag (item code KV-LL1.C2)
  • Android 10" TABLET

·       All-in-One Contact 2 is scalable , per user selection, in future to serve the following different types of tests :

Kit CONTACT3 for sonic and ultrasonic measurements on concrete specimens, walls, stone materials.
- Kit MCHA for checking posts and diaphragms.
- Kit  P.I.T for Pile Integrity Test through vibrational methods such as Echo test and admittance
