Application :
The tester is used to determine the Heat Derlection Temperature or the Vicat Softening Point. All the specimens are charged with a constant load and immersed in a bath, where temperature is increased at a standard velocity. The attained heat resistance rate of plastic material is a widely required parameter for product characterization,for quality control,as well as for'evaluating their conformity to the previewed applications.The optional software system enables to produce graphs showing the deformation of each specimen and temperature increase versus time.

HDT/V3 Series,
HDT/V 3116 ranks top-class in the world, which is embodied in the following advantages:
1.Automatic lifting mechanism provides stable and reliable performance.
2.The performances of specimen frame lift,offload, limit space, load can be finished during the lifting procedure,which make the breakthrough in the world.
3.The dispersion of testing result for standard sample is smaller than 0.5ºC,even under the smallest load condition.This technology has ranked among the international top level.
4.As exclusive design in the world,automatic smoke exhaust system has been designed to guarantee user's health and not contaminate the environment.
5.Application of digital micrometer with communication interface brings the top class performance in mechanic & electronic controlling ability and software technology.
6.Temperature protective circuit,being independent of the controlling system, is designed to protect the tester when the temperature of medium exceeds using range.

HDT/V1 Series "HDT" test means The test determines the temperature at which a specified deflection occurs when a standard test specimen is subjected to a bending stress, to produce one of the nominal surface stresses according to international standards. This test is important for both quality control and research into plastics.
"VICAT"test means The test determines the temperature at which a standard indenter penetrates 1mm into the surface of a test specimen under load. lt is used to establish the difference between many types of thermoplastic materials with regard to their softening properties.
