The figure below represents typical sensitivity characteristic all data having been gathered at standard test conditions (se reverse side of fhis sheet). The Y-axis is indicated as sens* fc(Rs/Ro] which is defined as follows:

The rigure below represents typical temperature ; dependency characteristics. Again, the Y axis is sensor resistance ratio {RsiRo), defned as follow Rs = Sensor resistance at 50ppm of ami at various temperatures/humidi Ro = Sensor resistance al 50ppm of at 20"C and 65% R.H.
