Ideal for “on worker” short-term or full shift sampling, the AirChek 52 personal sampling pump can be used for STEL, TWA or Ceiling sampling using single sorbent tubes. This unit is the workhorse of air sampling pumps for industrial hygiene studies or environmental testing. This battery-operated pump weighs only 20 ounces, and its modular pneumatic system provides constant flow in a range of 750 to 300 ml/min, reducible to 5 to 500 ml/min with the constant pressure controller. Flow is compensated with up to 25 inches water backpressure and moderated with a built-in pulsation dampener. As backpressure increases, the motor voltage corrects automatically for constant flow, so there is no sacrifice in accuracy, even in dusty environments. If flow is restricted for more than 15 seconds, the pump shuts down automatically, but the timer retains the valid run time.
The result of extensive research and development, 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.
The SKC Vac-U-Chamber is a rigid air sample box that allows sample bags to be filled directly by using negative pressure provided by most personal air sample pumps. Since the air sample does not pass directly through the pump, both pump and sample contamination are eliminated. The Vac-U-chamber's rigid walls will not collapse under vacuum conditions. All surfaces in contact with the sample are constructed of stainless steel or PTFE for inertness.
The Leland Legacy High Volume Sample Pump is a portable instrument with a range of 5 to 15 L/min. This pump also features high flows and long run times for low levels and 24 hour high flow.
Accurate air volumes without the need for frequent sample pump adjustments, smooth air flow 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)
Ensure integrity of results with shutdown on low battery, restricted flow, and excess back pressure; all with time-retention
Automatically corrects to maintain a constant flow
For low flow air sampling at 5 to 500 ml/min (requires the 224-26 series Adjustable Low Flow Holder accessory)
Built-in pressure regulator allows up to 4 tubes to be run simultaneously; reduces time in the field; uses fewer pumps
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)
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
Provides a minimum of 8 hours of continuous use per charge; battery charge test ensures pump lasts entire shift
Displays battery status, total sample time, delayed start, sample period, sample over, program setup, hold, and fault
Convenient program setup and display read out; 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
Designed for on worker applications; quiet enough for indoor air quality investigations
