The test machine is mainly used as cement, construction units and the relevant professional institutions and scientific research units to make the cement mortar flexural strength of the soft practice tests available, and can be used for other non-metallic brittle materials, the flexural strength test. 
 The single-lever testing machine maximum test force 1000N, use double leverage maximum test force is 5000N, test machine soft scale training exclusively for the cement mortar flexural strength and fracture resistance conversion scale, the maximum test force of 1000N When the value read is accurate to 0.4N and 0.001Mpa, when the maximum test force of 5000N is accurate to read out the value of 1N and 0.005 Mpa.
