The machines allow inexperienced operators to perform the test. Once the machine has been switched on and the specimen is positioned and centered by the help of concentric centering line/s of lower bearing block the only required operations are; Setting test parameters, including pace rate (only required when the specimen type is changed). Pressing the START button on the control unit. The machine automatically starts the rapid approach, when the specimen touches the upper platen the rapid approach is ended and starts loading at the pace rate that selected by user and stops once the specimen fails. Automatically saves the test parameters and test results. The Machines consist of a welded steel frame ( see table), hydraulic power pack with U-Touch PRO Control Unit. Main Features Safety Features U-Touch PRO Control Unit UTC-4930.FPR is designed to perform automatically compression, flexure and splitting tensile strength tests of construction materials such as concrete, cement mortar, masonary units/blocks by controlling the Utest automatic compression / flexure testing machines.

Curing temperature and curing time can also be set.
Used for the determination of the depth of penetration of water to hardened concrete specimens under pressure. 3 or 6 specimen capacity models and with and without quantitative measurement equipment of water penetratoion models are available. The system can test 150 mm and 200 mm cube specimens, Ø100x200 and Ø150x300 mm cylinder specimens. Up to 10 bar of working pressure is generated on the sample with compressed air applied to the integral water tank and controlled by a pressure regulator with a pressure gauge with 0,2 bar graduations. The test sets with the quantitative measurement equipment of water penetratoion the penetration of water is measured through the burettes. The system comprises impermeability gaskets for every cell. The measurement apparatus is supplied as standard. The apparatus has to be fitted with a suitable air compressor. The Air Compressor should be ordered separately.
