Draeger CH22901 questions
What does the Draeger CH22901 measure? Acetone in air, measuring range 100 to 12000 ppm.
How many pump strokes does the CH22901 take? 10 strokes (n) per the handbook, p. 121. Measuring time approx. 4 min.
Which pump does the CH22901 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 CH22901? light yellow → yellow, read against the scale printed on the tube.
Do Draeger CH22901 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 CH22901? 10. Each tube is used once.
