Other Measurement Technologies

  • Heikki Torvela


By the use of electrochemical measuring cells, it has become possible to construct portable measuring instruments which can simultaneously record concentrations of several gas components. In the instrument, there is a specific cell for each gas to be measured. Electrochemical cells have been produced to measure the concentrations of oxygen, carbon dioxide, carbon monoxide, hydrogen sulphide, nitrogen oxides and sulphur oxides from emission gases.
