The World’s Most Trusted Air Sampling Pumps. The Widest Flow Range of Any Personal Air Sampling Pump (1 – 5,100 cc/min). QuadMode™ Air Sampling Technology: Performs both high-flow constant pressure and constant flow (450-5,100 cc/min) and low-flow constant pressure and constant flow (20-499 cc/min) with a single pump. Selectable Automatic Fault Recovery: Ensures sample integrity by attempting to restart the pump in case of fault conditions. Standard Temperature & Pressure (STP) Correction: Provides accurate flow rate and volume measurements under varying environmental conditions (STP model). Superior Design & Comfort: Compact and lightweight design (one-third smaller than traditional pumps, weighing less than 21 oz.) maximizes worker comfort during extended sampling periods.
