1. Simple Introduction
It is mainly used for the determination of thermal deformation temperature and Vicat softening point temperature of non-metallic materials such as plastics, hard rubber, nylon, electrical insulating materials, long fiber reinforced composite materials, high-strength thermosetting laminate materials, etc. It is easy to operate and precise in control. It is a highly intelligent testing instrument, which is widely used in colleges and universities, scientific research units and product quality supervision and inspection units.
2. Test Standards
Comply with GB/T 1633, GB/T 8802, GB/T 1634, ISO 2507, ISO 75, ISO 306, ASTMD 1525, ASTMD 648 and other standards.
3. Characteristics
3.1 Single-chip control, Chinese characters LCD display temperature. Real-time button storage and query of test results.
3.2 Multiple safety protections: mechanical temperature upper limit protection switch and software temperature upper limit protection to ensure safe and stable operation of the test.
3.3 High-precision measurement and control system: the use of high-performance temperature sensor and advanced capacitive digital display dial indicator to accurately measure the small changes of the sample, the use of advanced PID algorithm and full photoelectric isolation phase modulation module for heating control, to ensure the heating The rate error is less than 0.5°C.
