CHUM
Cross Hole Ultra sonic Monitor
(CSL Tester) With tomography support
Overview
The CHUM (Cross Hole Ultrasonic Monitor) uses the Crosshole Sonic Logging, CSL testing method to perform high-resolution quality control of deep foundations.
The system uses an ultrasonic wave sent from a transmitter to a receiver pulled through water-filled access tubes embedded in the concrete. The measured arrival time and energy are strongly dependent on concrete quality. [ overview of this test method ] [ How to test a pile using CSL testing / the crosshole ultrasonic method? ]
Additional methods supported by the CHUM are Single Hole Ultra sonic Testing (SSL/SHUT) and Tomography (two- and three-dimensional).
The CHUM is fully compliant to ASTM D6760-16, AFNOR NF P 94-160-1 and additional standards

What makes CHUM crosshole logger, the fastest CSL testing equipment?
-
Easy to use
-
Usually, no training is needed, and the system can be self-taught in hours. (No expensive training days)
-
Supports AGC (Automatic Gain Control) for simple, fast, and accurate performance in dynamic conditions.
-
"Very, very easy to use..." - Barcelona, Spain
-
Tomography
-
2D tomography (included).
-
3D tomography provided as a service
-
Three alternative tomography methods: Fuzzy logic, Parametric and 3D
-
In real-time tomography: the shape of the defects forms as the probes are pulled
-
-
Modular design
-
CHUM connects to any PC via the standard USB port. It will connect to future computers (such as Origami) while embedded systems will quickly become outdated.
-
