XWB-300A/B Vicat Softening Point Apparatus is used to determine heat distortion temperature and vicat softening temperature of thermoplastic materials such as plastic, rubber .

XWB-300A/B (desktop/standard model), the span of sample frame is 60-180mm, the temperature range indoors is 300℃. It is single-chip computer controlled model, with three displacement sensors which determinate the deformations of the sample, the digital display shows the temperature displacement, and the micro printer prints test reports.
