Cross-sensitivity (handbook, p. 135): Other aromatics (toluene, xylene) are retained in the pre-layer. As a result, this also changes to a reddish brown color. If the concentrations of toluene or xylene are too high, the entire pre-layer through to the indicating layer is discolored, in which case a benzene measurement is not possible. Gasoline hydrocarbons, alcohols, and esters do not affect the reading.

Draeger 6718801 questions
What does the Draeger 6718801 measure? Benzene in air, measuring range 5 to 40 ppm.
How many pump strokes does the 6718801 take? 15 to 2 strokes (n) per the handbook, p. 135. Measuring time max. 3 min.
Which pump does the 6718801 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 6718801? white → reddish brown, read against the scale printed on the tube.
Do Draeger 6718801 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 6718801? 10. Each tube is used once.
