DIGITAL COMPRESSION TESTING MACHINE MODEL: CH32200 Used to test compression strength of building material just like concrete, cement and brick. It is designed and produced as per British Standard <Testing Concrete part 115. Specification for compression testing machines for concrete BS 1881: Part115> and some relative norms. Adopts loading hydraulically with accurate and reliable test data. In order to guarantee the accuracy of test load readout, it adopts oil pressure transducer to measure the load, after amplifying, the test load, peak value and loading speed can be displayed digitally. The oil source is installed at the bottom of control cabinet in which there is a double-flow high-pressure piston pump driven by the motor. The hydraulic loading system is controlled manually by the hydraulic valve with the functions of easy operation, safety and reliability. Further more, we adopt a hand wheel to adjust the testing space before the test. In this way, the specimen can be touched by the Sphere base upper plate easily.
