Non-metallic Materials Vertical Coefficient of Thermal Expansion Tester

The PZY-III-10/14/17 Non-metallic Materials Vertical Coefficient of Thermal Expansion Tester uses computer technology and intelligent instruments (microcontroller) to monitor and control physical quantities such as displacement and temperature throughout the entire experiment process. It supports offline operation and online automatic testing, running in a Chinese Windows environment with a user-friendly Chinese interface; manual testing is available in offline mode. This instrument is mainly suitable for determining the linear thermal expansion coefficient of pharmaceutical glass ampoules, complying with the 2015 edition of the National Pharmaceutical Packaging Material Standard average linear thermal expansion coefficient method (YBB00202003-2015). It can also test the expansion and contraction of aluminum alloys, non-metallic materials, graphite carbon materials, ceramics, rubber, plastics, and other composite materials in a molten state, as well as measure the coefficient of thermal expansion. Equipped with a protective gas interface, the sample preparation method complies with GB/T32158-2015 and GB/T3074.4 standards. The vertical design is aesthetically pleasing, practical, reliable, and convenient for sample loading. Product features include an industrial-grade color touchscreen with microcomputer control, clear visuals, sensitive touch, and ease of operation. The test process is intelligently controlled, with displacement and temperature monitored throughout the experiment. The instrument offers selectable vertical single or double pushrod types for convenient sample loading. It has strong compatibility with samples, capable of measuring the coefficient of thermal expansion for glass rods, tubes, plates, and finished products. Software processes data to automatically calculate the linear expansion coefficient and obtain expansion rate curves. The testing system automatically analyzes and calculates the expansion coefficient and linear expansion amount. The system displays and records temperature-expansion coefficient curves, all raw data, and calculates the linear expansion coefficient. It supports test data recording, storage, and viewing, and is equipped with a micro printer for direct output and printing of test results. Multi-level user permission management with password login facilitates user management. The instrument includes a built-in air cooling device that quickly cools the furnace body after the experiment, enabling rapid preparation for the next test and greatly improving testing efficiency.
