CDT1000 microcomputer-controlled electronic pressure testing machine is a new type of material testing machine combined with electronic technology and mechanical transmission, it has a wide and accurate loading speed and force range, the load, displacement measurement and control has a high degree of accuracy and sensitivity, but also can be isochronous loading, isochronous displacement of the automatic control of the test. It is specially used to test the compressive strength of cementitious sand material, which fully meets the national standard GB/T17671-1999 “Test Method for Strength of Cementitious Sand”, and also meets the test requirements for cementitious sand material of ISO and ASTM standards.
