The specimen is given a stress at the center, and the temperature should increase by 2 degrees Celsius per minute. When the specimen\u2019s center area reach the deflection of 0.254mm, the temperature is determined as the specimen\u2019s deflection temperature.<\/span>
The tester is equipped with touch screen. A user-friendly interface and standardized process are designed to guide users for setting operation 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.<\/span>
User should lift the specimen holder and the weight frame manually. This tester has 6 test stations, each one can show the independent temperature and displacement on the display. When reaching the deflection value, it will be recognized as test finish, the system will record the temperature and start to cool down.<\/span><\/p>\n<\/div>\n
