HDT Heat Distortion Temperature Standard Vicat Softening Point Apparatus
Equipment overview
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.
Features
Multiple security protection: Mechanical temperature upper limit protection switch, software temperature upper limit protection, to ensure 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.
