Polytevo Series HDT and Vicat Softening Temperature Tester
Product Detail
Polytevo Series HDT and Vicat Softening Temperature Tester (ACS-5006-TC3) is a three-station heat deflection temperature (HDT) and Vicat softening temperature (VST) tester with a temperature range of RT to 300°C, two selectable heating rates, a 25 L oil bath and computer-controlled operation.

The ACS-5006-TC3 measures the heat deflection temperature and Vicat softening point of non-metallic materials such as plastics, rubber, nylon and electrical insulating materials. A PLC programmable controller regulates the temperature and a computer displays and operates the test; temperature and deformation are monitored in real time, heating stops automatically at the end of the test, and the test report and curves can be printed. It can run heat deflection and Vicat tests on various standard specimens, also at the same time.
