Cross-sensitivity (handbook, p. 271): Other chlorinated hydrocarbons are also indicated, but with different sensitivities. A trichloroethylene measurement is not possible in the presence of free halogens and halogen hydracids in their OEL ranges, as these are also indicated. Gasoline hydrocarbons cause the reading to be shortened.

Draeger 6728541 questions
What does the Draeger 6728541 measure? Trichloroethylene in air, measuring range 20 to 250 ppm / 2 to 50 ppm.
How many pump strokes does the 6728541 take? 3 /5 strokes (n) per the handbook, p. 271. Measuring time approx. 1.5 min / approx. 2.5 min.
Which pump does the 6728541 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 6728541? light gray → orange, read against the scale printed on the tube.
Do Draeger 6728541 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 6728541? 10. Each tube is used once.
