The 30t (ton) cement constant stress pressure testing machine meets the international standard iso679, the national standard GB / t17671-1999 and the old national standard GB / t177-85. The loading speed is adjustable from 0.3 to 10kN. Input different speed to automatically calculate the test results according to the standard. The standard speed is 2.4kn/s, or 5.0kn/s. It has the function of independent calculation and storage at the same time. The single chip microcomputer works as usual without computer, which greatly reduces the failure rate.

The imported proportional valve has high stability and stable loading speed. There is no manual oil delivery valve return valve, real automatic constant stress press. Windows version of the operating software is simple and easy to use, ten minutes to learn. The software is free to upgrade, and the latest version can be downloaded from the Internet at any time.
