Draeger 8103251 questions
What does the Draeger 8103251 measure? Hydrogen fluoride in air, measuring range 0.5 to 15 ppm / 10 to 90 ppm.
How many pump strokes does the 8103251 take? 10 /2 strokes (n) per the handbook, p. 199. Measuring time approx. 2 min / approx. 25 s.
Which pump does the 8103251 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 8103251? violet-blue → yellow, read against the scale printed on the tube.
Do Draeger 8103251 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 8103251? 10. Each tube is used once.
