OVERVIEW
Equipment description:
HZ-1708B Thermal deformation, Vicat softening temperature testermainly used for the thermal deformation of the polymer materials (plastics, rubber, nylon, electric insulating materials, etc.) and Vicat softening point temperature determination. Apply to universities, research institutes and Product Quality Supervision and Inspection unit.Heated media inside the 45 ° double helix automatic mixing system, the tank has a special structure, temperature uniformity, and maintain the accuracy of ± 0.5 ° C. And the use of advanced thyristor-controlled temperature, displacement sensor has a fine-tuning, fine tuning the dual adjustment method,with emergency stop switch, the structure of the locked door after the Control Panel, machine maintenance, easy maintenance, the lift system as one of the models to reduce the noise. Therefore, the medium temperature gradient is uniform, constant temperature limit is reached when the test temperature to stop heating automatically when the set temperature, the test frame with automatic lift function, simple operation, with excellent cost performance in similar models.
