Air sampling in your shirt Pocket!

Featuring all-in-one design (sampling tube, pump, battery)
for colorimetric indicator, charcoal or other absorber tubes.

• Battery, pump, electronics and detector tube all in one
  compact, rugged module — eliminates cumbersome Tygon
  tubing and charcoal tube holder clipped to lapel.
• Light (4 oz.) and compact, with flame retardant case.
• Special clip ensures unit stays firmly in pocket.
• Flow range: 5 — 200cc/minute.
• Full flow regulation. A constant voltage is applied to pump as
  battery voltage drops.
• Low power consumption. A low cost (< $2.00) alkaline battery is
  sufficient for a 40-hour work week.
• Easily replaceable 9-volt battery. NiCad, zinc-carbon and
  alkaline types are interchangeable.
• Adaptable — accepts 6mm diameter (single and double) and
  8mm diameter charcoal tubes, other absorber tubes and Draeger
  & Kitigawa colorimetric tubes.
• Intrinsically safe. Current-limiting resistor in battery circuit prevents danger of short-circuit spark.
