levels
—General requirements and test methods, state that the concentration indicated by the output
signal shall not vary from the test gas concentration by more than a volume fraction of ±0.3% v/v over
the range 10% - 25% v/v oxygen. When exposed to other gases. Therefore, the 0-25% range Oxygen
Sensor - Electrochemical (177872) may read high when exposed to concentrations of carbon dioxide
exceeding 5%.
