1.1 The Tunnel Tech 500 Serie Concept
Tunnel Tech 00 Series is an all-new tunnel atmosphere monitoring system designed exclusively for road
tunnel applications. It offers a family of monitors that provide all the essential measurements necessary to
monitor a tunnel atmosphere for:
- Carbon Monoxide
- Nitric Oxide
- Nitrogen dioxide
This is achieved by using a modular design concept so that the users’ precise monitoring requirements can be
satisfied with a minimum number of components, minimum tunnel cabling and minimum installation costs. It
also offers a variety of data outputs to enable simple acquisition of data.

The monitoring stations, Figure 1, provide all required measurements and outputs at each monitoring location
within the tunnel.

1.2 CO, NO, and NO2
CO, NO and NO2 are measured using electrochemical cell technology. Once the zero level of the cell is set and
recorded in the instrument memory, the cell output is linear and proportional to the ppm or ppb reading.
A serial data link via an RS48 interface allows communication directly with the TunnelTech 00 sensors.
The PSU is required to convert the mains (90-263V AC) supply to the 24V DC required to power the TunnelTech
00.
