SENSOR VICONOX 

The VICONOX Tunnel Atmosphere Monitor is a single sensor solution for measuring NO2, NO, (NOx), CO, visibility, and temperature (or combinations of) within a road traffic tunnel, rail tunnel, or other confined space. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection.

The VICONOX has been designed for harsh tunnel environments with a high quality IP67 rated stainless steel housing. Wall-mounted alignment brackets, quick-release heads, and quick-lock cable connections make installation and future service easy and simple. VICONOX smart heads have RS485 (Modbus RTU), digital relays and analog outputs as standard for connection to a PLC / SCADA system.
