This machine is designed for determining the heat deflection temperature(HDT)of the plastic samples (the temperature at which the plastic samples (the temperature at which the plastic samples is penetrated by a needle under specified load.
This machine can be cooled by either the compressor or the water cooling system. The use of the compressor can effectively and rapidly reduce the temperature and save water used for the water cooling system. All metals immersed in heat transfer oil at high temperature are the alloy steels with low coefficient of deformation,so it can minimize the material deformation at hightemperature and improve the accuracy of the test result. It is characterized by heating, cooling, controlling stir automatically and displaying the temperature at the measured point automatically, With the high-precise LVDT displacement sensor measuring teh deformation of the indenter and ,the deformation of the indenter and the deformation-detecting amplifier developed, it is high in resolution and accurate in detection without data fluctuation.
The product is up to the stantandard: ASTM-D648 D1525,JIS-K7191,K7206,ISO-2507,GB/T8802.1634,1633
