J&R Technology Explosion Proof SIP/VoIP Phone

The Explosion Proof Telephone is designed for voice communication in the hostile environment where reliability, efficiency and safety are of prime importance. The telephone can handle large temperature differences found outdoors, high humidity, exposure to sea water and dust, corrosive atmospheres, explosive gases & particles, as well as mechanical wear and tear, making it perfect for use as an emergency telephone.

The unique robust handset is manufactured from moulded Bulk Molding Compound and designed specifically to withstand arduous use in all environments, armoured cord to provide additional resistance to vandalism or heavy industrial use.

The Explosion-proof and Weatherproof Telephones are designed for use by the chemical plant, Coal Mine,power stations, the armed services and heavy industry which require very reliable and explosion protection telephony under adverse conditions.
