What does the Draeger 6733141 measure? Styrene in air, measuring range 10 to 250 ppm.
How many pump strokes does the 6733141 take? 20 strokes (n) per the handbook, p. 256. Measuring time approx. 3 min.
Which pump does the 6733141 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.
