Cross-sensitivity (handbook, p. 181): Styrene, vinyl acetate, and acetaldehyde are also indicated with a yellow-brown color. Acrolein, diesel fuel, and furfuryl alcohol are also indicated with a yellow-brown color. 500 ppm octane, 5 ppm nitric oxide, and 5 ppm nitrogen dioxide have no effect.
Measuring range extension (handbook, p. 181): The measuring range can be extended in conjunction with the activating tube (order no. 81 01 141). Evaluation takes place on the 20-stroke scale. The indicated scale value must be divided by F: 0.1 to 1.25 ppm with 40 strokes, F = 2; 0.05 to 0.63 ppm with 80 strokes, F = 4; 0.04 to 0.5 ppm with 100 strokes, F = 5

Draeger 6733081 questions
What does the Draeger 6733081 measure? Formaldehyde in air, measuring range 0.5 to 5 ppm / 0.2 to 2.5 ppm.
How many pump strokes does the 6733081 take? 10 / 20 strokes (n) per the handbook, p. 181. Measuring time approx. 1.5 min / approx. 3 min.
Which pump does the 6733081 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 6733081? white → pink, read against the scale printed on the tube.
Do Draeger 6733081 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 6733081? 10. Each tube is used once.
