HDT/VICAT Systems offer Heat Distortion Temperature (HDT) and Vicat Softening Point of plastic materials. Qualitest offers a single station economical Heat Deflection tester, while the BK - 3000 Systems and HDT Series Heat Deflection Tester offer sophisticated control using Windows-based software.

Applications：

Lightweight and compact HDT/VICAT tester. It is designed to measure heat deflection temperature and VICAT softening temperature for evaluation of thermal property of plastic materials.

Bench type HDT/VICAT tester. It is designed to measure heat deflection temperature and VICAT softening temperature for evaluation of thermal property of plastic materials. This tester features high precision temperature ramp rate control. LVDT sensor is used on each station to ensure high accuracy of deflection measurement.
