Digital H.D.T. Heat Deflection Tester
Confirm to ASTM D648 ISO 75-1 Standard
The specimen is given a flexion stress at the center, and the temperature should increase by 2 degrees Celsius per minute. When the specimen’s center undergoes a deflection of 0.254mm, the temperature is determined as the specimen’s deflection temperature. The tester is equipped with touch screen that guides users step by step. A user-friendly interface and standardized process are designed to orientate users in the shortest possible and to reduce test errors. The system has built-in calculation function, user can enter the specimen dimension to get the required weight. During the process, the specimen holder and the weight frame automatically rise and descend to facilitate specimen’s installment. This tester has 6 test stations, each one can show the independent temperature and displacement on the display. When it reaches deflection value, it will record the temperature and stops and start cooling system. Smart testing process is time-saving and requires only a minimum of testers.
