(NOTE)
1)This detector tube is affected by ambient temperature and humidity,therefore, it is necessary to compensate
the reading of gas detector tube with the following equation and correction coefficient table.
Actual concentration＝Reading Value×Correction Coefficient
2)In case of 6 pump strokes, following formula is available for the actual concentration.
Actual concentration＝1/2×Temp./R.H. corrected value
