DID YOU KNOW?
Some electrolyte compounds react with multiple gases. This is what we term a ‘cross gas effect’, the effect of this is results in a false mA output of the cell for the gas measured. Electrochemical CO cells industry-wide, can be affected by other gases, some typical gases which can influence your CO reading are; H2 and H2S however others do exist.
For removal of H2S from the gas mixture we supply an H2S / VOC filter which uses activated carbon to remove all H2S within the mixture. We also offer a unique H2 compensated (up to 1%) version of our CO sensor, to help when monitoring CO in the presence of H2. If H2 is above 1% this could permanently damage the cell. For full information on best practise monitoring in the presence of H2 please contact Geotech.
