Heat Deflection-Vicat Softening Temperature Tester

According to GB/T 1633, ISO 75, ASTM D 1525

For the determination of heat deflection temperature and Vicat softening temperature of thermoplastics, thermosets and other polymer materials

Adopts a guided medium flow diversion structure, delivering a uniform temperature field without dead zones

Test frame expansion <±0.01mm over full temperature range, no correction needed
