Casella Apex Pro Air Sampling Pump Rental $25.00 $60.00 $180.00

The Casella Apex Pro is a portable air sampling pump with a digital display. It is capable of datalogging information such as start and stop times, flow rate, average sample temperature, and total volume sampled. The flow rate can easily be adjusted and calibrated. The Casella Aprex Pro makes tedlar bag sampling simple with the 'bag' flow rate setting. This setting allows the pump to sense when the tedlar bag is full and automatically shut off. The Casella Apex Pro has programmable settings such as Time Weighted Averages (TWAs) and start & stop times. It is capable of flow rates as low as 5 mL/min to 5 L/min.
