PUNDIT plus - Ultrasonic Instrument



PUNDIT Plus is low frequency ultrasonic concrete test equipment for field or laboratory use, with data storage and computer output facilities. PUNDIT Plus enables the detection of cracks, voids and other imperfections in concrete and reinforced concrete. Pundit Plus is also used for quality control purposes, for testing concrete strength.
