Descripción
The NOVICOM tunnel monitor measures the concentration of nitric oxide (NO) and carbon monoxide (CO) in tunnel atmospheres and makes a visible opacity measurement to determine the visibility within the tunnel. These measurements can be used as part of an air quality management system for ventilation control and/or secondary smoke detection within a traffic tunnel or other confined space.
FEATURES
- Proven infrared spectroscopy technique for measurement of nitric oxide (NO) and carbon monoxide (CO)
- Data output for total oxides of nitrogen (NOx)
- Visibility measurement using the widely accepted light transmission opacity technique
- Temperature and humidity compensated measurements to ensure stable readings across all tunnel conditions
- IP65 / NEMA 4X rated external enclosure supplied with quick release dust protection tubes and wall brackets
- Intelligent analyser with optional Operator Interface
- Choice of interface options enabling easy integration into tunnel control system
BENEFITS
- Designed specifically for monitoring in tunnels
- Rugged design to withstand corrosive atmosphere and regular tunnel washing
- Simple installation and alignment
- Low maintenance requirements
- Suitable for right or left hanging to enable compliance with regulations governing light emissions facing on-coming traffic flow
