BPIT, Inc. - Low Volume Air Sampler LV-40BW

Low Volume Air Sampler LV-40BW


This suction pump is intended for measuring work environments and ambient environments. It is portable and supports both AC and DC power supplies. By preparing a battery unit, there is no need to take into consideration the power supply situation of whether or not the measurement point has a power outlet. It also incorporates various functions such as constant flow rate, total flow rate and timer operation

  • Compact, lightweight, and handy to carry around
  • Drops in suction flow rate caused by an increase in the sampling amount are suppressed by a constant flow rate unit
  • The pump incorporates a timer function. The ON timer operates by the time and countdown modes, and the OFF timer operated by the time, countdown, and total flow rate timer modes.
  • The instantaneous and total flow rates, pressure loss and other values are displayed digitally.
  • Brushless motor is used to suppress dust emission and extend motor life
  • The pump can also be driven by a DC battery by using the battery unit (sold separately)
  • The battery unit uses an overcharge protection circuit
  • The battery charger (sold separately) can charge up to three battery units simultaneously.
