CHUM – Cross-Hole Testing Equipment

Crosshole Sonic Logging (CSL) method for high resolution quality control in deep foundations.

High accuracy and ease of use

The system uses an ultrasonic wave sent from a transmitter to a receiver pulled through water-filled access tubes embedded in concrete. The arrival time and measured energy of the ultrasonic wave depend strongly on the quality of the concrete

Conforms to ASTM D6760-16, AFNOR NF P 94-160-1

The CHUM connects to any PC via the USB port to create a powerful CSL drive.
