氧/二氧化碳O2,CO2气体检测管281S
1. PERFORMANCE
1) Measuring range：
Oxygen 2-10 ％
Carbon dioxide 1-20 ％
Number of pump strokes 1(100ml)
2) Sampling time ：8 minutes/1 pump stroke
3) Detectable limit ：0.001 ％
4) Shelf life ：1.5 years
5) Operating temperature ：0～40℃
6) Temperature compensation：
Oxygen Necessary(See "Temperature CorrectionTable")
Carbon dioxide No temperature correction is necessary.
7) Reading ：Direct reading from the scale calibrated by 1 pump stroke
8) Colour change：
Oxygen White→Brown
Carbon dioxide Pink→Yellow
2. RELATIVE STANDARD DEVIATION
Oxygen RSD-low：10％ RSD-mid.：10％ RSD-high：10％
Carbon dioxide RSD-low：10％ RSD-mid.：10％ RSD-high：10％
3. CHEMICAL REACTION
Oxygen：Oxygen reacts with alkaline pyrogallol.
Carbon dioxide：CO2＋2KOH→K2CO3＋H2O
4. CALIBRATION OF THE TUBE
Oxygen?Carbon dioxide STANDARD GAS CYLINDER METHOD
5. INTERFERENCE AND CROSS SENSITIVITY
Ordinary combustion gases do not affect the reading value and discolouration.
5. CONCENTRATION CORRECTION
On account of interaction of indication between carbon dioxide and oxygen, the true concentration is calculated
by the following equations.
［EXANPLE］
At the measuring temperature of 30℃, when oxygen indication is 5％(temperature corrected value 5.3％)and
carbon dioxide indication is 10％, each true concentration is calculated as bellow.
Accordingly true concentration :
Carbon dioxide 9.47％
Oxygen 4.77％
