ASTM D648 ASTM D1525 Vicat Softening Temperature Test Machine Of Plastics is used to measure the thermoplastic specimen under certain load, under the condition of constant temperature, sample is 1 mm squared pressure needle into 1 mm when temperature (hereinafter referred to as vicat temperature) as well as the determination of the thermoplastic plastic sample of simply supported beam with constant temperature and is under the action of static bending load, e. when the temperature of the sample to special equipment (hereinafter referred to as thermal deformation temperature).The microcomputer controlled test process is adopted to display the test temperature value, test time and deformation curve equivalent in real time.Multiple samples can be tested simultaneously.
It is especially suitable for inspection, development and research of products and materials produced by pipe manufacturers, product quality inspection stations, construction engineering quality inspection stations, construction companies, scientific research institutions and other institutions.
Thermal deformation and vicat softening point tester adopts PLC programmable controller for temperature adjustment and touch screen display operation.The product is simple to operate, convenient to use, stable in performance, high in precision, and in the test process can be real-time monitoring of the test temperature and deformation;At the end of the test, the system automatically stops heating, and the test curve can be displayed.This series of machines are the self-testing instruments of quality inspection units, colleges and universities and enterprises.
