Draeger 8101731 questions
What does the Draeger 8101731 measure? Toluene in air, measuring range 100 to 1800 ppm.
How many pump strokes does the 8101731 take? 10 strokes (n) per the handbook, p. 268. Measuring time approx. 1.5 min.
Which pump does the 8101731 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.
