The Pocket Pump 20 to 225 ml/min miniature PC-programmable personal sample pump provides up to 12-hour run times for sampling gases/vapours. The pump is ideal for use with sorbent tubes. The Pocket Pump is UL Listed for intrinsic safety. 
Constant flows from 20 to 225 ml/min  
  • Accommodates typical flow rates for sorbent tubes 
  • Model available with twin ports for bag sampling 
Compact and lightweight
  • Only 4.5 x 2.2 x 1.4 inches (11.4 x 5.6 x 3.6cm) and 5 ounces (142 grams)
  • Easily fits a shirt pocket or clips on a belt
Advanced technology with manual and PC compatibility 
Save time and use fewer pumps with multiple-tube sampling 
  • Sample with up to 4 tubes simultaneously; select from two pump modes:
  • Constant flow mode, requires multiple-tube low flow holder and CPC 
  • Constant pressure mode, requires multiple-tube low flow holder only
PC programmable with DataTrac Software
  • Program delayed start, timed run, or multiple sampling schedules 
  • Download sampling data to a PC for record keeping and data analysis
No tools required
  • Simple 3-button keypad does it all
Continuous sample volume calculations
  • All sampling parameters are continuously updated 
Automatic features maintain sample integrity
  • Low battery and restricted flow shut off
  • Pump stores run time data in memory
  • Auto-restart attempted after flow fault 
RFI/EMI-shielded and CE marked
  • Flow unaffected by outside interferences
  • Accurate air volumes and data validity ensured 

Large easy-to-read LCD

  • Displays sampling parameters, battery status, and flow fault at the touch of a button 
Smart charging
  • Built-in system automatically senses maximum charge and switches to trickle charge to prolong battery life and prevent damage 
Continuous run with AC adapter for extended sampling 
  • Useful for environmental monitoring or 24-hour sampling without harm to the battery pack 
Constant battery status display 
  • View battery status before, during, and after sampling 
Security code protects data
Impact-resistant case
  • Rugged case withstands rough handling in the industrial workplace 
Intrinsically safe
  • UL and cUL Listed 
  • Model available that meets ATEX Directive 94/9/EC (NiCad battery model only) 
  • Safe in hazardous locations 
  • Versatile for all industries
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 Accuracy ± 5% of set-point in constant flow after calibration
Pressure Range in Constant Pressure (Multiple-tube Sampling) Mode (inlet only) 

1 to 10 inches of water (1.87 to 18.7 mm Hg) at a maximum flow rate of 200 ml/min for 8 hrs (12 hrs if using NiMH battery)
10 to 20 inches water (18.7 to 37.4 mm Hg) at maximum flow rate of 100 ml/min for 8 hrs (12 hrs if using NiMH battery)

Constant Pressure (Multiple-tube Sampling) Mode Accuracy  Pressure reading ± 0.5 in of water (0.25 mm Hg) 
Operating Temperature  32° to 113°F (0° to 45°C) 
Storage Temperature  -4° to 113°F (-20° to 45°C) 
Charging Temperature  40° to 100°F (5° to 38°C) 
Operating Humidity 0 to 95% non-condensing
Tubing Requires 1/4-inch ID tubing
Run Time 

With NiMH: 12 hours at 200 ml/min and 10 inches water back pressure, 12 hours at 100 ml/min up to 20 inches water back pressure

Run time is 8 hrs at either setting if using NiCad battery 
Varies with flow rate and sampling media in line 
Using a charger with AC power: Extend run time 
Timer Display Range  1 to 9999 minutes 
Timing Accuracy  ± 1% 
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.
