What does the Draeger 8103031 measure? Water vapor in air, measuring range 3.0 to 60 Ibs/mmcf.
How many pump strokes does the 8103031 take? 3 strokes (n) per the handbook, p. 279. Measuring time approx. 90 s.
Which pump does the 8103031 use? A Draeger tube pump: the accuro hand pump or the X-act 5000.
