Característica
ASTM B117 chamber JOEO dust sand test chamber dust proof chamber is made for the simulation of dust and sand conditions. These sand and dust chamber used to test the exposure of test the exposure of automotive and electronic components under extreme environmental conditions in order to validate product seal.Dust ingress test methods included IEC60529, ISO20653 and many others.
The airflow circulates upward from the bottom, blowing the dust circulation,forcing dust around the specimens. All models are upgrade to programmable controller and Ethernet access that provides simple operation and control.
Blowing sand and dust test chamber door attached to the window, the door to the lower part of the electrical control area,Simulated sand dust of talc in the lower hopper of the test chamber. Use the of circulating fan and automatic jar will be blown into the upper network studio talcum powder through a 75 micron square hole,The test space form high density dust shape, test specimen.
