The Vertex VX-427 two way radio is powerful and built for durability. The Vertex VX-427 radio is Intrinsically Safe (IS), offering the best protection in a volatile, hazardous chemical or gaseous atmosphere. The Vertex VX427 also offers 5 watts of transmit power, support for 16 channels and 6 programmable function keys. Channel scan and monitor functions are also supported. These professional radios offer a great value and provide a high level of performance and reliability in dangerous environments.

The Vertex VX 427 is designed for safe operation in explosive atmospheres. The VX-427 is Intrinsically Safe which ensures that the electrical and thermal energy of the radio is low enough that ignition of the hazardous atmosphere cannot occur. Other two-way radios contain equipment that can create internal tiny sparks and such sparks can ignite flammable substances present in the air. The VX-427 meets the requirement set forth in ANSI/UL 913 6th Edition for Class 1, Division 1, Groups A-D; Class II, Groups E-G; and Class III for hazardous locations.
