Brief Introduction of Structure Design
This dust test equipment has selected high-quality materials, used the most advanced processing equipment inChinaat present for the processing formation. With coordinate color collocation, arc-type design, smooth and natural line, the outer covering surface is beautiful and smooth after spurts models processing. Made of the imported high-quality stainless steel, the inner container is designed as a airtight space that can set the test sample to conduct the outer covering sealing test. With reasonable design and durable structure, the indoor sample holders and other accessories are made of stainless steel plate.
The device itself has an excellent sealing performance, the condition of the laboratory test can be seen clearly; Equipment is equipped with a set of vacuum system to meet the needs of the test; The bottom of the equipment is assembled with replaceable dust device and movable roller wheels to make convenient move.
This equipment not only meets the national standards and has the stable performance, but also is practical and easy to have more control. In addition, this equipment is easy to install and operate, and basically doesn’t need daily maintenance.
