Cross-sensitivity (handbook, p. 247): A maximum 6 ppm sulfur dioxide or 15 ppm hydrogen chloride does not affect the reading. Higher concentrations result in plus errors. – Ammonia (> 100 ppm) results in minus errors. – Arsine is indicated with a different sensitivity. – Hydrogen sulfide is indicated with a different sensitivity. – 30 ppm hydrocyanic acid does not affect the 3-stroke measure- ment. Minus errors of up to 50 % occur in the 10-stroke meas- urement.

Draeger 8101611 questions
What does the Draeger 8101611 measure? Phosphine in air, measuring range 0.1 to 1.0 ppm / 0.01 to 0.3 ppm.
How many pump strokes does the 8101611 take? 3 / 10 strokes (n) per the handbook, p. 247. Measuring time approx. 2.5 min / approx. 8 min.
Which pump does the 8101611 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 8101611? yellow → red, read against the scale printed on the tube.
Do Draeger 8101611 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 8101611? 10. Each tube is used once.
