The AirChek® 2000, 5 to 3250 ml/min, PC-programmable personal sample pump provides over 12-hour run times for sampling particulates and gases/vapors. The pump is ideal for use with sorbent tubes, filter cassettes, and size-selective samplers.

The AirChek 2000 is UL Listed for intrinsic safety.
Schedule it on a PC! 
Combine AirChek 2000, your PC, and DataTrac 2000 Software to easily create single or multiple sampling schedules that include delayed start, timed shutdown, and sequential sampling. Alternatively, a single schedule can be set manually using the pump’s large integral keypad. 
Sample and record it! 
Start sampling with the click of a mouse or the press of a button. A patented (U.S. Patent No. 5,892,160) internal flow sensor acts as a secondary standard to accurately maintain set flow. AirChek 2000 records flow rate, run time, sample volume, and flow fault throughout the sampling period. View values on a PC in pump history or during sampling on the pump LCD. 
Download and report it! 
Use your PC and DataTrac 2000 Software to download pump history, import data into your favorite software for IH lab reporting, or create a worker exposure profile for complete reporting. 
CalChek it! 
The CalChek automatic calibration feature provides hands-free calibration between an AirChek 2000 pump and a Defender primary standard calibrator. This results in highly accurate single-point calibration for pre and post-sampling and complete multiple-point calibration following pump maintenance. 
Partner the AirChek 2000 pump and CalChek with your PC and DataTrac 2000 Software for documented results of calibration for ISO 9000, quality programs, and occupational health and safety management systems. 
Patented* isothermal flow control system
Accurate internal flow sensor measures flow directly and acts as a secondary standard to maintain set flow with an accuracy of ± 5%. Thermal and pressure sensors maintain flow calibration by compensating for differences between the temperature and atmospheric pressure at calibration and those during sampling.
* US Patent No. 5,892,160
Longer run times
With NiMH battery pack, run time is 12+ hours at 2000 ml/min and up to 30 inches water back pressure; dependent on sample media used
Battery status display 
Indicates battery power available to operate pump
Wide flow range — 5 to 3250 ml/min
AirChek 2000 is the best choice for many sampling applications. 
Low flow capability
With the easy-to-use low flow adapter kit, achieve flows from 5 to 500 ml/min (low flow does not include some electronic readout options). 
Easy PC programmability
Combine AirChek 2000 and a PC with DataTrac 2000 Software to easily create multiple sampling schedules that include delayed start, timed shutdown, and sequential sampling or download sampling data to a PC for storage and analysis. 
Compact, lightweight, and ultra-quiet
For greater worker acceptance
Intrinsic safety
Versatile for all industries and safe in explosive environments; UL and cUL Listed
Continuous sample volume calculations
Flow rate, run time, volume, and flow fault are continuously recorded for accurate sample reporting.
RFI/EMI-shielded, impact-resistant case
Ensures accurate air volumes and data validity; covers protect battery charging jack and computer interface port; CE marked
Security system protects data
A security code minimizes accidental changes and maintains sample validity. 
Multiple-tube sampling feature
Save valuable time with simultaneous 2, 3, or 4-tube sampling
Protective features
Auto shut-off at low battery; automatic flow fault shutdown and restart
Performance Profile
Flow Range
1000 to 3250 ml/min (5 to 500 ml/min requires optional low flow adapter kit)
Compensation Range
3000 ml/min at 15 inches water back pressure
2000 ml/min at 30 inches water back pressure
1000 ml/min at 30 inches water back pressure
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. During flow fault, the pump enters Hold, the fault icon appears on the display during the length of the fault, and the accumulated run time display is frozen and retained. After 5 minutes in flow fault, auto-restart is attempted every 5 minutes up to 10 times.
Run Time
With NiMH battery pack, run time is 12+ hours for 2000 ml/min and up to 30 inches water back pressure; dependent on sample media used. 
With Battery eliminator, run time is extended.
Charging Time (varies with battery capacity and level of discharge) 6 to 8.5 hrs with PowerFlex charger
Flow Accuracy ± 5% of set-point after calibration to desired flow
Flow Control
An internal isothermal flow sensor measures flow directly and continuously. Sensor readings are used in a flow monitoring algorithm to maintain calibrated volumetric flow. In addition, built-in atmospheric temperature and pressure sensors provide readings to correct volumetric flow for these parameters when they vary from point of calibration.
Atmospheric Pressure Accuracy ± 0.3 in Hg
Timing Accuracy 1 min/mo at 25°C
Operating Temperature Range         32° to 113°F (0° to 45°C)
Charging Temperature Range    50° to 113°F (10° to 45°C)
Storage Temperature Range    -4° to 113°F (-20° to 45°C)
Altitude The pump can apply correction to volumetric flow during sampling for weather-related or altitude variations from the atmospheric pressure established at calibration up to at least 7500 feet above and 5000 feet below sea level.
