The AirChek® 52, 5 to 3000 ml/min, easy-to-use personal sample pump provides up to 12-hour run times for sampling particulates and gases/vapors. The pump is ideal for use with sorbent tubes, filter cassettes, size-selective samplers, and impingers. The AirChek 52 is also UL Listed for intrinsic safety. 

  • Flow range of 1000 to 3000 ml/min
    Ideal for most personal sampling applications including sorbent tubes, filter cassettes, impingers, and size-selective samplers, and long-duration detector tubes; high flow range of 1000 to 3000 ml/min; low flow range of 5 to 500 ml/min requires low flow accessories
  • Constant flow compensation
    Provides constant flow within ± 5% for accurate air volumes
  • For both high and low flow applications
    Eliminates the need for separate sampling pumps for high and low ranges when using the optional Constant Pressure Controller (Cat. No. 224-26-CPC) and Adjustable Low Flow Holder (Cat. No. 224-26 series) 
  • Minimum controls for easy operation
    Two pumps in one easy-to-use sampler
  • RFI/EMI shielded and UL Listed for intrinsic safety
    Case material and unique circuitry are designed to provide shielding from radio frequencies in the range of 27 to 1000 MHz, UL Listed for intrinsic safety for Class I, Division 1 and 2, Groups A, B, C, D; Class II, Division 1 and 2, Groups E, F, G; and Class III, Temperature Code T3C; CE marked; ATEX-approved model available
  • Highly accurate display
    • Digital time display tracks sample run time in minutes up to 99,999 
    • Indicates low battery condition or flow fault without losing sample run time
    • Attempts auto-restart up to 5 times from flow fault 
  • Low flow sampling capabilities
    With low-cost, lightweight Constant Pressure Controller and adjustable flow holder accessories 
  • Multiple-tube sampling capabilities
    • Optional multiple low flow holders used with a CPC allows up to four tube samples to be taken simultaneously, each at different flow rates

Run Time
NiCad Battery: 8 hrs minimum at above compensation ranges; dependent on media used. 
NiMH Battery: 12 hrs minimum at 2000 ml/min and up to 25 inches water back pressure; dependent on media used.
Power Supply
Rechargeable 4.8-V nickel-metal hydride (NiMH) battery pack, 3.3-Ah capacity or Rechargeable 4.8-V nickel cadmium (NiCad) battery pack, 1.8-Ah capacity A battery eliminator is available ; use voids the UL Listing for intrinsic safety.
Battery Charging Time (varies with battery capacity and level of discharge) 6 to 8.5 hrs using PowerFlex Charger
Operating: 32° to 113°F (0° to 45°C)
Storage: -4° to 113°F (-20° to 45°C)
Charging: 50° to 113°F (10° to 45°C) 
Humidity  0 to 95% non-condensing
Flow Fault If pump is unable to compensate for longer than 15 seconds due to excessive back pressure, the pump enters flow fault. During flow fault, the pump stops, the fault icon appears on the display, and elapsed time remains on the display. Auto-restart is attempted up to 5 times. Elapsed time information will be lost on restart. 
Low Battery Fault
LCD displays low battery icon and pump shuts down. LCD remains on.
LCD Time Display
LCD display shows elapsed pump run time in minutes up to 99,999.
LCD Indicator LCD always remains on. Displayed elapsed run time information resets when pump is started.
