A portable ultrasonic concrete-testing apparatus Available to Purchase

The new apparatus described is basically similar to the Road Research Laboratory ultrasonic equipment but has been designed to be more convenient for field testing work. It has been built in two separate units for easy portability and the weight has been reduced to approximately half that of the original apparatus. It is still necessary to provide an a.c. mains supply for the equipment. A number of new features have been incorporated, providing greater convenience in use and servicing.
