(NOTE)
1)When the concentration is below 0.5ppm, 2 pump strokes can be used to determine the
lower concentration. Following formula is available for the actual concentration.
Actual concentration＝1/2×Reading value
In case of 1/2 pump strokes, following formula is available for actual concentration.
Actual＝2×Reading value
2) Read the concentration rapidly because the discoloured layer will be faded gradually.
Substance Interference ppm Coexistence
Ammonia 60 From gas inlet side of discoloured
layer, the discolouration is faded.
Hydrogen selenide Similar stain is produced. Higher readings are given.
