Brief introduction of equipment:
This laboratory equipment is suitable for carrying out some reliable tests on industrial products under high and low temperature (variable) environment, which can be combined with the main machine at random according to the different requirements for using environment. It can be used to complete the tensile, compression and shear tests of various metal and non-metal materials at high and low temperature, as well as meet the using needs of various special industries, such as plastics and rubber. If testing at room temperature, it just needs to remove the environmental cabinet, or not to increase/decrease the temperature in the environmental cabinet. Its temperature controller adopts human-machine interface (HMI), and is combined with central arithmetic unit and intelligent PID fuzzy control mode, so as not to cause any test temperature overshoot, which is of high control precision, good stability, color interface, intuitive, and easy to operate.
