SKC PCXR8 Universal Sampling Pump

SKC PCXR8 Universal Sampling Pump



The result of extensive research and development, the PCXR8 air sampling pump is a constant flow personal or area 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 sample pump is ideal for industrial hygiene studies as well as environmental testing. Specifically designed for “on-worker” and “fenceline” applications. Back pressure compensation to 40 inches of water, automatically corrects to maintain a constant flow.

The PCXR8 comes with a built-in low flow pressure regulator at no extra cost. For low flow air sampling at 5 to 500 ml/min (requires the 224-26 series Adjustable Low Flow Holder accessory). Its long-life NiCad battery provides a minimum of 8 hours of continuous use per charge; battery charge test ensures pump lasts your entire shift.
