Overview:

This explosion-proof digital telephone station has dual explosion-proof performance requirements of intrinsic safety and explosion-proof, and meets the requirements for hazardous areas in explosive gas environments in Zone 1 and Zone 2. It can be applied to fields such as petrochemicals, coal mines, metallurgy, energy, transportation, etc.

Adopting a zinc aluminum alloy shell with a thickness of 5mm, it is sturdy and durable, with good sealing performance. The surface is sprayed with outdoor anti UV powder coating, which is environmentally friendly and does not fade when exposed to long-term outdoor sunlight. The design includes an anti damage earpiece made of imported PC and ABS synthetic materials, with stainless steel flexible hoses and an internal design of anti damage tensile steel rope, with a tensile strength of 200KG or more.

With excellent noise suppression function, it can adaptively learn the noisy environment in noisy environments and filter it out. Only the voice of the caller can be heard, but the environmental noise cannot be heard.

Featuring integration, high reliability, and high protection level. The design of the off hook fork is unique, using non-contact magnetic induction devices; The dial-up keyboard adopts a fully sealed touch type metal backlit keyboard.

Equipped with explosion-proof, dustproof, anti-corrosion and other functions, it meets the requirements of the national standard GB/T15279-94 for telephones.
