Draeger 6723301 questions
What does the Draeger 6723301 measure? Styrene in air, measuring range 10 to 200 ppm.
How many pump strokes does the 6723301 take? max. 15 strokes (n) per the handbook, p. 255. Measuring time max. 3 min.
Which pump does the 6723301 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.
