Description SKC Pocket Pump is an advanced low flow sample pump combining light weight and compact design with PC compatibility. When used with SKC sampling media such as sorbent sample tubes, the Pocket Pump is efficient and accurate for performing TWA, STEL, and Ceiling sampling for organic gases and vapors.
Performance Profile Flow Range in Constant Flow Mode: 20 to 225 ml/min Accuracy Variance Between LCD Reading and Actual Flow Rate (after calibration): 20 to 225 ml/min ± 5% Constant Flow Compensation Range (inlet only): 20 to 225 ml/min up to 20 inches water back pressure Flow Control: Holds constant flow to ±...

Performance Profile Timer: 1 to 9999 min display ± 1% accuracy 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.
Battery Installation/Charging Installing/Replacing the Battery Pack To enhance battery life, SKC ships battery packs separate from the pump. Completely charge a new battery pack detached from the pump before installing. Completely charge the new battery pack detached from the pump (see page 6).

(see page 6). Do not charge or operate the pump with the charger in hazardous locations. Use only the SKC-approved battery pack designated for the Pocket Pump to ensure reliable performance and to maintain the SKC warranty and UL Listing for intrinsic safety.
Do not charge or operate the pump with the charger in hazardous locations. Ensure the computer interface port is covered before, during, and after charging. Failure to follow warnings and cautions voids any warranty. The battery pack may be kept on the SKC-approved charger for an Note: indefinite time.
If FAIL still displays, there is a fault in the pump electronics. Send the pump to SKC for repair. Use only SKC-approved batteries to ensure reliable performance and intrinsic safety. Using a non-approved charger voids any warranty and could damage the pump...
Battery Installation/Charging Determining Battery Charge Level • The pump will operate for up to 12 hours with a NiMH battery (eight hours with NiCad) at a flow rate of 200 ml/min and back pressure of 10 inches of water. Pump operation time will increase as flow rate and back pressure rates are decreased.
Introduction Interpreting Pump Operating Terms In this manual, “run time data” refers to all the terms listed below: FLOW: Flow rate in milliliters per minute (ml/min) VOLUME: Total volume of air in milliliters (ml) or liters (L) since reset PRESSURE: Pump back pressure measured in inches (ins) of water or millimeters (mm) of Hg TEMP: Temperature of incoming air in C or F...
Setup Operating the Keypad The Pocket Pump operates by pressing various sequences of the three keypad buttons located beneath the sliding cover. Operate the Pocket Pump with the follow- ing key sequences: Pocket Pump Keypad Star Button • Scrolls through run time data and setup options displayed on the LCD Up and Down Arrow Buttons ...
Setup Determining Pump Operating States • The pump is sampling and run time data is updated continuously in memory. HOLD • The pump is not sampling and run time data is stored. Hold displays on the LCD. • Temperature and back pressure readings are still active and shown on the LCD.
Setup Setting Up the Pump To activate the pump: • Press any keypad button. The LCD will show the pump serial number for two seconds followed by a firmware revision number. To obtain run time data: • Press the button repeatedly to scroll through run time data. To reset the data display to zero: •...

Setup To change the temperature scale display: • In enhanced display and with the pump running, press: [] to place in HOLD, to enter Setup, and [] Press to scroll to the temperature display. The display will show the newly selected temperature scale.
2. Set the pump for Constant Flow mode (see pages 12 and 13). 3. Using a length of tubing, connect the pump inlet to a representative sorbent tube using an SKC tube holder. 4. Connect the exposed end of the tube to a primary standard calibrator using another length of tubing.

Operation Press . ADJ will appear on the LCD. The pump flow rate can now be calibrated using a calibrator. See reminder below. 10. When the flow rate reading appears on the calibrator, press the or buttons on the pump keypad to adjust the flow up or down until the calibrator displays the desired flow rate.
Operation Calibrating and Sampling in Constant Flow Mode — Multiple Tubes For use with constant pressure controller and multi-port adjustable low flow tube holders The Constant Pressure Controller (CPC) (Cat. No. 224-26CPC-10) is a pump accessory that provides a simple alternative for multiple sorbent tube sampling while in Constant Flow mode.
Page 22
Operation Label all tubes and ports (e.g., tube #1, port A). Insert opened representative tubes into the ports. Place unopened tubes in any unused ports to “seal” them. This is essential to obtain correct results. Loosen the flow adjust screw on the low flow tube holder port containing the tube to be calibrated.
Operation Calibrating and Sampling with Bags Requires Twin Port Pocket Pump Cat. No. 210-1002A Inlet Outlet (exhaust) Twin port Pocket Pump sampling train with bag Calibration Before use, allow the pump to equilibrate after moving it from one temperature extreme to another. Ensure the pump is set in Constant Flow mode (see pages 12 and 13).
Page 24
Operation Press to lock in the calibrated flow. The pump will then enter its normal RUN state. 10. Press [] to place the pump in HOLD. Press (security code) and to reset the data display to zero (minutes that have elapsed during pump setup and/or programming) before sampling.
Advanced Operation Calibrating and Sampling in Constant Pressure Mode — Multiple Tubes For use with multi-port adjustable low flow tube holders only. Calibration Before use, allow the pump to equilibrate after moving it from one temperature extreme to another. Ensure the pump has run for five minutes before proceeding with calibration. Set the pump to enhanced display and Constant Flow mode (see pages 12 and 13).

Advanced Operation Obtain the calculated back pressure by adding one inch to the highest back pres- sure number and rounding up to the next number. The additional inch allows for typical back pressure fluctuations. Example using two tubes: Flow Back Pressure Tube Port (ml/min)
