OVERVIEW
Product summary:
HZ-1749 Computer type heat distortion temperature test machine used to test the HDT of plastic test sample.
It also can test the temperature when the plastic sample under controlled test conditions so that to happen
constant needle penetration phenomenon(VICAT softening temperature).At the same time it can display test
sample heated temperature and distortion quantity.When reached to the test condition,it has the tweeting prompt
and oil pumping functions.
Product features:
HZ-1749 Computer type heat distortion temperature test machine can elect compressor cooling or water cooling.
The former can cool quickly and save water consumption in the cooling-off process.All the metal material which
are immersion in high temperature heat transfer oil are low deformation coefficient copper alloy. The machine can
make the material high temperature deformation reduce to the minimum and improve the the test result accuracy,
with rising temperature,reducing temperature,mix automatically controlled function.It can automatically display test
point temperature.Adopts high accuracy LVDT displacement sensor to measure deformation of indenter.
