FD-50D explosion-proof equipment,hot sale exploder

1.got the MA mark and Explosion-proof Certificate 2.use in danger of methane, gas 3.small,light 4.good quantity.

Usage

Use special tools to open the shell back cover then put into the battery before use. Attention the battery polarity can’t opposite. Don’t touch the face of exploder-proof. Tighten the screws after put into battery. It can be used with an explosive mixture of methane and coal dust coal mine.

Certificate:

The exploder got the MA mark and Explosion-proof Certificate issued by CQST. (CQST is mutual recognition with Norway’s NEMKO, Germany’s PTB, America’s UL\FM, Australian’s TESTSAFE, France’s LCIE\INERIS, Britain’s BASEEFA, Russia’s CCVE, Netherlands’s KEMA, Japan’s TIIS and so on.)

Remarks:

Exploder should kept by the hand, regular three-month overhaul, and the exclusion of internal tide, the establishment of maintenance records. The overhaul of the Exploder, the main performance indicators must be qualified, or not use.
