COMPANY PRODUCT

1. Simple Introduction
It is mainly used for the determination of heat distortion temperature and Vicat softening point temperature of non-metallic materials such as plastic, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high strength thermosetting laminates. It is easy to operate and precise in control. It is a highly intelligent test instrument widely used in colleges and universities, research institutes and product quality supervision and inspection units.
 
2. Test Standards compliant 
ISO 2507 Thermoplastics pipes and fittings Vicat softening temperature Part 1: General test method
ISO 75 Plastics -Determination of temperature of deflection under load
ISO 306 Plastics.Thermoplastic materials.Determination of Vicat softening temperature (VST)
ASTM D 1525 Standard Test Method for Vicat Softening Temperature of Plastics
ASTMD 648 Standard Test Method for Deflection Temperature of Plastics Under Flexural Load in the Edgewise Position
 
3. Instrument Characteristics 
Multiple security protection:
The mechanical temperature upper limit protection switch and the software temperature upper limit protection ensure the safe and stable operation of the test.
High-precision measurement and control system:
 The high-performance temperature sensor and the advanced capacitive-type digital display dialimeter are used to accurately measure the small changes of the sample. The advanced PID algorithm and the all-optical isolation phase-modulation module are used for temperature control to ensure that the heating rate error is less than 0.5 °C.
