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 enclosure. Wall mounted alignment bracketry, quick release heads and quick lock cable connections make installation and future servicing easy and simple. The VICONOX’s intelligent heads have RS485 (Modbus RTU), Digital Relays and Analogue Outputs as standard for connection to a PLC / SCADA system.
