Constant flow air sample pump with a wide flow range
Accurate air volumes without the need for frequent sample pump adjustments, smooth airflow for high flow (750 to 5000 ml/min), pulseless for low flow (5 to 500 ml/min). Low flow air sampling applications require the optional Adjustable Low Flow Holder (Cat. No. 224-26 series)
Automatic fault features
Ensure integrity of results with shutdown on low battery, restricted flow, and excess back pressure; all with time-retention
Backpressure compensation to 40 inches of water
Automatically corrects to maintain a constant flow
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)
Multi-tube low flow air sampling capability
Built-in pressure regulator allows up to 4 tubes to be run simultaneously; reduces time in the field; uses fewer pumps
Small and compact air sampling pump
Measures only 5.1 x 4.7 x 1.9 inches (13 x 11.9 x 4.8 cm) and weighs 34 oz (964 gm)
Built-in rotameter and particulate trap
Provides a visible check of pump flow rate during air sampling; the filter assembly with see-through housing and trap protects the pump from debris and reduces maintenance requirements
Long-life NiCad battery
Provides a minimum of 8 hours of continuous use per charge; battery charge test ensures pump lasts an entire shift
Large easy-to-read LCD
Displays battery status, total sample time, delayed start, sample period, sample over, program setup, hold, and fault
Easy keyboard programming and control
Convenient program setup and display readout; interrupt/hold button permits shutdown for breaks, lunch, or to recheck the air sample pump; programmable for delayed start time, intermittent sampling, extended sampling up to 7 days, timed shutdown, and repeatability
Ultra-quiet operation
Designed for on worker applications; quiet enough for indoor air quality investigations
