1. Functional use of microcomputer-controlled constant stress pressure tester (2000KN/3000KN)

This series of products is mainly used for mechanical properties tests of concrete, high-strength concrete, cement components and other materials. This series of products adopts a computer to fully automatic control of the test process, uses an electro-hydraulic servo system to control the loading, and an electric lead screw to adjust the test space, and has automatic and manual loading functions. Depending on the test requirements, hosts in different spaces can be configured. Complete the entire test process according to the stress rate or pre-set curve form, with dynamic display functions of load, rate, time and test curve. After entering the test parameters once, all tests can be automatically completed in sequence.
