TunnelCraft - Model III - CO/Visibility Air Quality Monitor (AQM)

by Codel International Ltd

The TunnelCraft III CO/VIS Air Quality Monitor (AQM) uses infrared light and visible light to measure carbon monoxide and visibility in a single compact instrument. The AQM consists of a transceiver that projects infrared beams to a reflector unit mounted 3m away. The reflected light is received by the transceiver and the specific absorption is ...

TunnelCraft - Model III - CO/NO/VIS Air Quality Monitor (AQM)

by Codel International Ltd

The TunnelCraft III CO/NO/VIS Air Quality Monitor (AQM) uses both infrared light and visible light channels to measure carbon monoxide, nitric oxide and visibility in a single compact instrument. The AQM consists of a transceiver that projects infrared beams to a reflector unit mounted 3m away. The reflected light is received by the transceiver ...

TunnelCraft - Model III - Visibilty Air Quality Monitor (AQM)

by Codel International Ltd

The TunnelCraft III Visibility Air Quality Monitor (AQM) uses visible light channels to measure the visibility within a tunnel environment. The AQM consists of a transceiver that projects visible light to a reflector unit mounted 3m away. The reflected light is received by the transceiver and the specific absorption is measured to determine the ...

TunnelCraft - Model III - Air Flow Monitor

by Codel International Ltd

The Air Flow Monitor (AFM) uses ultrasonic technology to measure air velocity. A single transmitter and an array of four receivers are contained in the measuring head. Air velocity and direction are calculated from measurements of the phase shifts from the ultrasonic signals at the receivers. The sensor is compact, contains no moving components, ...

TunnelCraft - Model III - NO2 Air Quality Monitor (AQM)

by Codel International Ltd

Nitrogen dioxide (NO2) is fast becoming the most important measurement in tunnels and will eventually replace nitric oxide (NO) as the key measurement. The TunnelCraft III NO2 Air Quality Monitor (AQM) uses a high-power blue LED to measure the attenuation of UV/blue light by NO2 in the tunnel atmosphere. The AQM consists of a transceiver that ...

OSi - Model WSS-300-DS - Tunnel Wind Speed And Smoke Sensor

by Optical Scientific Inc. (OSi)

For drift-free air flow measurements across traffic tunnels; WSS-300-DS calculates true average speed of air movement, and detects smoke. The sensor is equipped with Automatic Gain Control (AGC) to compensate for  opacity variations caused by particulates, smoke, or suspended moisture. The WSS-300-DS uses patented optical scintillation ...

Model VICONOX - Visibility Monitor for Tunnels

by Tunnel Sensors Limited

The VICONOX tunnel monitor is a single sensor solution for measuring NO2, NO, CO, visibility and temperature within a 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.

JES - Model ECS300-T - Electrochemical CO Sensor

by JES Elektrotechnik GmbH

The electrochemical CO sensor is mounted in the tunnel's traffice area, i.e. directly at the sampling point. The sensing element is contained in a shock resistant plastic housing which again is mounted in a stainless steel housing with intake cowl and protection against water ingression. Available either as wall-mounted or flush-mounted box or ...
