Anticrash Protective Case

As the world's more bad weather, when people use the precision instrument in the outdoors , will inevitably encounter shock, water, acid and alkali corrosion or pressure difference caused by excessive burst etc.. Using our safety case, the U.S. military standard material (corrosion resistance); waterproof sealing ring (-40℃ low temperature resistance; water pressure 21psi, 1 meters under water for half an hour without water seepage); polymer row pressure filter valve (keep the body inside and outside pressure equal), can solve these problems effectively.
