Typical industy applications include oil and gas, automotive, aviation and marine refueling and transport, chemical processing and manufacture, furniture manufacturing and other industrial manufacturing, processing and maintenance operations where hazardous, combustible gases and airborne particles are present and where worker safety and reliable communications are paramount.
Easy integration NEXEDGE® digital ATEX / IECEx hand portable radios feature Mixed Mode, which enables them to automatically recognise and communicate with any existing analogue radios in your fleet; allowing you plan a phased migration to the benefits of digital.
Rugged and durable NX-230EX/330EX radios are fully compliant with U.S. Department of Defence environmental standards for US MIL-STD 810 C/D/E/F/G for: Low Pressure, High Temperature, Low Temperature, Temperature Shock, Solar Radiation, Rain, Humidity, Salt Fog, Dust, Vibration, Shock and Immersion.
