Flow Fault
If the pump is unable to compensate for longer than 15 seconds due to excessive back pressure, the pump enters FLOW FAULT mode. The pump goes into HOLD, the fault icon appears on the display, and the accumulated run time display is frozen and retained. After 5 minutes in flow fault, auto-restart is attempted every 5 minutes until flow is corrected.

Pocket Pump showing labeled parts 210-1000 Low Flow Pumps The Pocket Pump ® 210 Series

The Three-button Keypad Does It All
Use the three buttons under the sliding cover to operate the Pocket Pump at flows from 20 to 225 ml/min. Set the flow rate in constant flow mode for single sorbent tube applications, or set the back pressure in constant pressure mode for multiple-tube applications. The Pocket Pump accommodates flow ranges for most sorbent tube and long-duration detector tube methods. Users may also select the temperature and pressure scale. Security code protected operating mode and parameters minimizes tampering and maintains sample validity. The Pocket Pump may be placed in HOLD mode at any time without loss of data.

The Pocket Pump operates in either constant flow (single-tube sampling) or constant pressure (multiple-tube sampling) mode with flows from 20 to 225 ml/min. Operation is programmed using the three-button keypad or a PC.

A built-in security code system prevents workers from changing operating state or parameters, ensuring sample validity. Multiple keys must be pressed to place the pump in HOLD; accidentally pressing one button will not alter pump operation.

Direct Readout of Data
The large easy-to-read LCD shows direct readouts of sample data that is continuously updated and may be displayed during sampling at the touch of a button. Simply press a key to scroll through the sample data that includes flow rate, air volume, temperature of the incoming air, and sample time. The LCD constantly displays a battery status icon, and a flashing flow fault icon appears when flow is restricted or blocked.

Pump-controlled Charging
Never worry about overcharging again. Since advanced electronics are built into the pump and not the charger, the smart charging battery system knows how much charging the pump needs; it never overcharges. The batteries may be charged with the battery charger while the pump is running. The Pocket Pump may operate indefinitely with the AC charger/adapter without harm to the battery pack.

The battery charge status icon is constantly displayed. When the pump loses all charge, it enters SLEEP mode while preserving the historical data in memory. When fully charged, the NiMH battery provides 12 hours of continuous use at 200 ml/min with back pressure up to 10 inches of water. Run times vary with media used.

PC Programmable with DataTrac Software
Use DataTrac Software (optional accessory) and your personal computer to make the Pocket Pump PC programmable. DataTrac simplifies chain-of-custody reporting by allowing users to program up to 14 complete running sequences including delayed start, and timed run. Pump settings can be changed with the click of a mouse button. DataTrac’s Real-time Monitor window displays a real-time readout of the Pocket Pump’s operations including time and sample volume. Lengthy calculations are unnecessary; DataTrac does it all for you. The advanced information retrieval system is specifically designed to store data and provide chain-of-custody information. DataTrac also stores historical data in pump memory that can be retrieved up to 24 hours after shutdown.

  • Program the flow rate, start and stop date, and sample duration.
  • Schedule multiple start and stop times.
  • Create a sample setup sheet for worker, sample, and analysis information.
  • Download historical records of flow rate, sample time, air volume, temperature, and more.
  • Print or save a complete report of sample and pump history information.
