Measuring range: 140-1,400 μ/㎥; 70-210 μ/㎥
Sampling volume: 9L (300mL/min×30min); 18L（300mL/min×60min）
Sampling time: 30 minutes/ 60 minutes
Shelf life: 1 year (Necessary to store in refrigerated conditions; 0～10℃)
Operating temperature: 5～35℃
Operating humidity: Below 16mg/L (0～70%R.H. at 25℃, 0～40%R.H. at 35℃)
Reading: The tube scales are calibrated based on Toluene at sampling volume of 300mL/min×30min and Xylene concentration is determined by multiplying the tube reading by 1.4 at sampling volume of 300mL/min×30min and by 0.7 at sampling volume of 300mL/min x 60min
