CO sensor Viconox

nitrogen dioxideNO2NO

The VICONOX tunnel atmosphere monitor is a single sensor solution for measuring toxic gases, visibility and temperature within harsh tunnel environments. Features NO2 MEASUREMENT Direct optical measurement of nitrogen dioxide (NO2) using differential absorption VISIBILITY MEASUREMENT Visibility measurement using an accepted light transmission opacity technique INFRARED SPECTROSCOPY Proven infrared spectroscopy technique for NO and CO measurement INSTALLATION Quick lock plug and socket cable connection enabling simple installation OUTPUTS RS485 communication (Modbus RTU), Digital Relays and Analogue outputs EXTENDED WARRANTY Optional extended warranty and 5 year refurbishment programs are available Tunnel atmosphere monitor 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. Benefits Pre-aligned quick release TX and RX heads enabling easy installation and maintenance Up to 6 measurement parameters in one unit minimises capital cost but also minimises the requirements for cabling, installation and commissioning Temperature and humidity compensated measurements to ensure stable readings across all conditions Rugged design to withstand corrosive atmospheres and regular tunnel washing
