Personal Air Samplers
|
Air sampling in your shirt Pocket
 |
FEATURES:
- 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.
BASIC UNIT CONSISTS OF:
- PAS-500 Sampler
- Holder for 6mm charcoal tube
- Screwdriver
- Instruction Manual
- 9-volt battery
|
No more cumbersome Tygon tubing and charcoal tube holder clipped
to your lapel - the PAS-500 fits neatly in your shirt pocket.
|
The 9-volt battery easily slips in and out. |
Flow-control and on/off
switch are easily accessible. |
Two units using charcoal and calorimetric tubes - saves cost
of charcoal tube analysis if color tube is negative. |
