Draeger 6733181 questions
What does the Draeger 6733181 measure? Ozone in air, measuring range 0.05 to 0.7 ppm.
How many pump strokes does the 6733181 take? 10 strokes (n) per the handbook, p. 239. Measuring time approx. 3 min.
Which pump does the 6733181 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 6733181? light blue → white, read against the scale printed on the tube.
Do Draeger 6733181 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 6733181? 10. Each tube is used once.
