Australia Tunnel Air Quality Monitoring Systems
POGC have supplied CODEL Australia tunnel air quality monitoring system, Tunnel Master or Tunnel Craft 3 air quality monitor (AQM), to three major road tunnels in New South Wales: The Eastern Distributor Tunnel, the Cross City Tunnel and the Lane Cove Tunnel. We also offered industrial stack emission monitoring system for major power station and industrial power plant.

TunnelCraft and Tunnel Master Low-Cost Precision Sensors
The Air Quality Monitor (AQM) uses both infrared and visible light channels to measure carbon monoxide (CO), nitric oxide (NO) and visibility (VIS) in a single compact instrument.

The AQM consists of a transceiver that projects visible and infrared beams to a reflector unit mounted 3m away. The reflected light is received by the transceiver and the specific absorption is measured to determine the visibility dimming coefficient, carbon monoxide and nitric oxide concentrations within the path of the beams.

CO and NO concentrations are derived using gas cell correlation infrared absorption technology, to provide accurate, low-drift measurements.

Visibility is measured using visible light transmission from a high-power modulated LED, enabling high accuracy measurements to be obtained without interference from other light sources within the tunnel.
