Larger series sand and dust test chambers allow for large and more quantity specimens, a capacity of 1500 liters and 2000 liters as standard. Great for laboratories and large industrial products. Sand and dust test chambers are made for the simulation of dust and sand conditions. These dust test chambers are used to 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, MIL-STD-810G, and many others. The airflow circulates upward from the bottom, blowing the dust circulation, forcing dust around the specimens. All models are upgraded to programmable controller and Ethernet access that provides simple operation and control.
