What should I pay attention to when purchasing mine explosion-proof camera?

Product selection must meet the safety standards of the place of use, such as explosion-proof, explosion-proof grade and group. When there are two or more explosive mixtures of different grades and groups in the area, the appropriate explosion-proof type should be selected according to the higher risk grade and group.

Explosion-proof products have signs and signs, and the signs (nameplates or warning signs) are made of copper. In addition to the product model, specification, manufacturer's name, factory date or factory number, there are also "Ex" signs, explosion-proof signs and explosion-proof certificate numbers. Mine explosion-proof electrical products should have "Ex" mark, "MA" mark, explosion-proof mark and explosion-proof certificate number, and MA coal mine safety mark certificate number;

Explosion-proof electrical products imported from abroad must be inspected and approved by China's explosion-proof quality inspection institutions;

Carefully distinguish fake and inferior products. The main performance is that there is no explosion-proof certificate number on the sign, the certificate number of the explosion-proof camera is forged, there is no manufacturer, and the workmanship is rough.
