High-low Temperature Tensile Testing Machine is used for high-low temperature (variable) reliable testing for industrial products according to the different using environment,can be used with host machine in random.It can be used for tensile,compression,shearing test of all kinds of metal and non-metal materials can meet with the requirement for special industrial (such as plastic, rubber industry etc).For normal temperature testing,just need to move the testing cabinet(or doing the testing in the cabinet without fluctuation of temperature. The temperature controller adopts human-computer inferface combined with central arithmetic unit and intelligence PID fuzzy control method. The testing temperature not overshoot.High control accuracy. Good stability.Colored interface.visual and easy to operate.
