Description
The Draeger Tube Hydrogen Sulfide 0.2/b 8101991 is a precise and cost effective way to measure the amount of hydrogen sulfide vapor in the air.
Application Range
Standard Measuring Range: 0.2 to 6 ppm
Number of Strokes n: 1
Time for Measurement: approx. 55 s
Standard Deviation: ± 15 to 20 %
Color Change: yellow → pink
Ambient Operating Conditions
Temperature: 15 to 40 °C
In case of temperature between 0 °C and 10 °C, multiply the reading by 1.5; standard deviation: ± 30%.
Absolute Humidity: max. 20 mg H2O / L
Reaction Principle
H2S + HgCl2 → HgS + 2 HCl
HCL + pH indicator → pink reaction product
Cross Sensitivity
Up to 1000 ppm, sulfur dioxide has no influence on the reading. Within the range of their TLV, mercaptanes, arsine, phosphine and nitrogen dioxide are also indicated, however, with differing sensitivity. Within its TLV, hydrogen cyanide changes the color of the entire indicating layer to a light orange. The reading of hydrogen sulfide is not affected.
