ASTM648 Three Working Positions Plastic Hard Rubber Nylon Soft Point HDT & VICAT Tester
ASTM648 Three Working Positions Plastic Hard Rubber Nylon Soft Point HDT & VICAT Tester
ASTM648 Three Working Positions Plastic Hard Rubber Nylon Soft Point HDT & VICAT Tester 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
1)Test stand lifting system: The automatic lifting function of the test stand greatly facilitates the operation of the test, improves the test efficiency and avoids personal injury.
2)Advanced control system: With high stability, it is easier to install, test and analyze.
3)Humanized software control system: The imitation digital tube displays the temperature and displacement, and draws the test curve. It provides a variety of coordinate curves for centralized management of the data. It can analyze the test data, print test curves, test data and test reports.
4)Four safety protection: Multiple hardware and software safety design such as mechanical temperature upper limit protection switch, software temperature upper limit protection, test completion automatic stop and administrator operation key to ensure safe and stable operation of the test.
5)High precision measurement and control system: The high-performance temperature sensor and the advanced capacitive-type digital display dial gauge 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 .
