The sand dust chamber helps to evaluate the ability of the equipment to withstand the effects of blocking the openings, the penetration of cracks, crevices, dust from bearings and joints, as well as to reduce the performance, efficiency and reliability of the impact due to the abrasive effect of the sharp edges of the large sand grains or the influence of the obstructions. Sex and maintainability. It is used to evaluate all mechanical, optical, electrical, electronic, electromechanical and electrochemical devices that may be exposed to dry blasting, dusting atmosphere or dust reduction conditions. This product is strictly in accordance with GB/T2423.37-2006 test L: sand dust test method, GB7000.1-2007 lamp housing protection, GB12085.6-89 and other corresponding national standard technical parameters design and manufacture, simulated dust environment test; Waterproof or Dustproof Test Chamber Waterproof Test Chamber,Dustproof Test Chamber,Sand Dust Aging Tester,Temperature Humidity Climatic Test Chamber Dongguan Jaten Instrument Co.,LTD(HK TT:Jaten Technology Co.,Ltd ​) , http://www.jatentech.com
