The high and low temperature testing machine is mainly suitable for rubber, plastic profiles, plastic pipes, plates, sheets, films, wires and cables, waterproof membranes, metal wires, metal rods, metal plates and other material products. It can be used at high, low and ultra-high temperatures. Comprehensive mechanical testing under medium conditions such as vacuum and inert atmosphere. It can also perform tensile, compressive, bending and other strength tests on metal materials at room temperature. Adding a material testing fixture can perform corresponding strength tests on materials or finished products.
