Product Description
The PCY-III-SG uses computer and microcontroller technology to monitor and control displacement and temperature. It supports offline manual testing and online automatic testing in a Chinese-language Windows environment. The method and specimen preparation follow GB/T 32158-2015 and GB/T 3074.4.
The horizontal dual-tube structure tests two specimens simultaneously or compares a standard specimen with a test specimen. Parameters can be set, adjusted, and locked through the computer.
