Falling Weight Impact Tester TFWT-A10 is mainly used to calculate impact resistance of thermoplastic sheets, pipes and plastic fittings under given specified conditions of impact by means of falling weight. It determines anti-impact properties of plastic pipes, sheets and other products. This impact tester is adopted with PLC control & digital touch screen technology for controlling parts like proper figure setup, zero adjustment, preset dropping height, raising & dropping hammer. Adopted with pneumatic technology to prevent secondary impacts with 100 % capture rate.
