Page 16: Principles Of Operation
TunnelTech500/700 Operating-and-Maintenance-Manual 2 Principles of Operation Electro-Chemical Cell: In order to measure the level of gas (CO/NO/NO ), the Tunnel Tech 700 uses an electro chemical cell to convert the gas in to readable data. The gas diffuses into the sensor and interacts with the electrode within the cell. This causes a chemical reaction in which the gas is reduced or oxidised.
