The PCXR4 is a constant flow air sampling pump suited for a broad range of applications. With an operating range of 5 to 5000 ml/min (low flow applications of 5 to 500 ml/min require an optional adjustable low flow holder), this battery-operated air sampling pump is ideal for industrial hygiene studies as well as environmental testing. Specifically designed for "on-worker" and "fenceline" applications.

The PCXR4 from SKC means a constant flow air sample pump with wide flow range, accurate air volumes without the need for frequent pump adjustments, smooth air flow for high flow (750 to 5000 ml/min), pulseless for low flow (5 to 500 ml/min). This all for a very competetive price.

Low flow air sampling applications require the optional Adjustable Low Flow Holder (Cat. No. 224-26 series). The LCD shows the sampling time recorded at the point of shutdown. Back pressure compensation to 40 inches of water and automatically corrects to maintain a constant flow.
