Cross-sensitivity (handbook, p. 203): Sulfur dioxide has no effect on the reading up to 1000 ppm. Mercaptans, arsine, phosphine, and nitrogen dioxide are also indi- cated in their OEL ranges, but with different sensitivities. Hydrocyanic acid in the OEL range discolors the entire indicating layer light orange. This does not affect the indication of hydrogen sulfide.

Draeger 8101991 questions
What does the Draeger 8101991 measure? Hydrogen sulfide in air, measuring range 0.2 to 6 ppm.
How many pump strokes does the 8101991 take? 1 strokes (n) per the handbook, p. 203. Measuring time approx. 55 s.
Which pump does the 8101991 use? A Draeger tube pump: the accuro hand pump or the X-act 5000. Per the handbook (p. 28–29), Draeger short-term tubes and Draeger tube pumps are matched at the factory and form a single unit; using other pumps with Draeger tubes, or other tubes with Draeger pumps, can impair the measurement.
What is the color change on the 8101991? yellow → pink, read against the scale printed on the tube.
Do Draeger 8101991 tubes expire? Yes. Draeger prints an expiration date (month and year) on the package; the handbook states a typical shelf life for the customer of up to two years, stored sealed at the temperature on the package strip (handbook section 2.13).
How many tubes are in a box of 8101991? 10. Each tube is used once.
