Product Description
● High-low Temperature Electronic Universal Testing Machine (High-low Temperature Chamber)
● This testing machine is used for high-low temperature ( variable) reliable testing for industrial products, according to the different using en-vironment, 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 industryetc). For normal temperature testing, just need to move the testing cabinet( or doing the testing in the cabinet wihout fluctuation of temperature The temperature controlle adopts human-computer inferface combined with central arithmetic unit and itelligence PID fuzzy control method. The testing temperature not overshoot,high control accuracy, good stability, colored interface, visual and easy to operate.
