PEX7 Explosion Proof Industrial VoIP Phone


Explosion Proof Industrial VoIP Telephone

PEX7 is an explosion-proof VoIP phone, specially designed for hazardous area communication. The ATEX telephone uses heavy metal as the raw material of the outer casing, and its housing is firm and vandal-proof. It can be used in emergency environments such as petrochemical mining and the like as emergency communication equipment.

PEX7 is an intrinsically safe phone, designed for use in nuclear power plants, chemical, petroleum, natural gas and other hazardous areas to provide intrinsically safe communications equipment. It is suitable for use in fires where the environment is filled with flammable gases, steam, dust, flammable vaporized liquids, or in an environment filled with flammable fibers in the air.

In the dangerous environments, PEX7’s normal work will not be the source of the explosion. The intrinsically safe phone PEX7 cast in a metal case, has a waterproof rating of up to IP66 and is dust and drop resistant.

PEX7 is certified by international IECEx and ATEX. The safety availability can be fully guaranteed. Its function is very powerful, we use VoIP communication, you can configure the phone in any PC, the configuration is simple, the call is stable, and the call is free.

Pearl’s new line of PoE-enabled SIP ruggedized phones combine the benefits of VoIP with a rugged designed phone, built to withstand harsh environments such as extreme temperature, bad weather, and vandalism.
