Spectrex PAS-500 Operating Manual

PAS-500 Personal Air Sampler

Purpose:

The PAS-500 is a Personal Air Sampler for moving air through an external collection
device, such as charcoal or other sampling tube. Weighing only 4 oz. and furnished with a
special "shirt-pocket clip", it can be worn in a shirt pocket or on a lapel.

Features:

- Battery, pump, electronics and detector all in one compact, rugged module.
Eliminates cumbersome Tygon tubing and charcoal tube holder clipped to lapel.
- Light (4oz.) and compact, with flame-retardant case.
- Special pocket clip ensures unit stays firmly in pocket.
- Flow range: 5-350 ml/min.
- Flow regulation: A constant voltage is applied to pump as
battery voltage drops.
- Low power consumption. A low cost (less than $2.00) alkaline battery is sufficient for
a 40 hour work week at 50cc/min.
- Easily replaceable 9-volt battery. NiCad, zinc-carbon, and alkaline types are
interchangeable.
- Adaptable – Accepts 6 mm 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 sparks.
- Optional clip set if wearer does not have a pocket.
