(NOTE)
1)This detector tube is affected by abmbient relative humidity,therefore,it is necessary to compensate the reading of
gas detector tube with the following formula and correction confficient table.
Actual concentration=Reading Value(ppm)×Correction Coefficient
2)In case of 2 pump strokes, following formula is available for actual concentration.
Actual concentration=1/2×Reading value corrected with above formula
