氫氣H2氣體檢測管137U HYDROGEN 0.05-0.8%

Tube 37U
1. PERFORMANCE
1) Measuring range :0.05-0.8%
Number of pump strokes 1/2(50ml)
2) Sampling time :0.5minutes/1/2 pump stroke
3) Detectable limit :0.03%
4) Shelf life :3 years
5) Operating temperature :0~40℃
6) Temperature compensation :Necessary(See "TEMPERATURE CORRECTION TABLE")
7) Reading :Direct reading from the scale calibrated by 1 /2 pump strokes
8) Colour change :Yellow→Green
2. RELATIVE STANDARD DEVIATION
RSD-low:10% RSD-mid.:10% RSD-high:10%
3. CHEMICAL REACTION
By reacting with Oxygen in Atomsphere, water vapour is produced. This Water vapour reacts with Magnesium
perchlorate and PH indicator is discoloured.
H2+O2→H2O
H2O+Mg(CIO4)2→Mg(CIO4)2?H2O
4. CALIBRATION OF THE TUBE
STANDARD GAS CYLINDER METHOD
5. INTERFERENCE AND CROSS SENSITIVITY

6.SPECIAL NOTE
1)The tube will not respond in the absence of oxygen.
2)When the concentration of Hydrogen is 12 to 16%, pretreat reagent gives a heat but is not dangerous for use
in hazardous area.
3)When the concentration of Hydrogen is over 40%, the reading value may be indicated below 0.8%.In this
case, the bottom of the discoloured layer becomes dark purple. In order to make sure that the concentration is
extremely high such as 40%, measure the gas concentration with connecting 2 tubes. If both tubes are
discoloured to green, extremely high concentration Hydrogen exists.
