Low-voltage electrical appliances, instruments, instruments, various lamps and other products, often affect the dust environment during storage, transportation and action, especially the effect of car electrical appliances is more significant, this equipment It is to use artificially simulated dust environments to test the test equipment for dustproof capabilities. The basic structure and principles and performance of this device are met to meet the requirements of national standards related to the dust test method, and it is also possible to provide a vertical circulating gas stream of non-layer-free dust, and has cyclic uses that observe
. Dust function and the circulating dust-free air flow can smoothly speed up and turn off automatic or continuous control, is an ideal dust test equipment. This device can provide corresponding environmental simulation and acceleration tests for scientific research, product development and quality control. Equipment meets national standards GB 2423.37-2006LA2 dust test method, GB 4208-2008 Shell protection rating (IP code), GB / T4942-93 Low-voltage electrical shell protection level, GB / T 10485-2007, GB 7001-96 Requirements for dust test.
