AEVP101, Calibration Device -- $949.00/each (calibration device for above AEVP100)
This calibration device monitors AEVP100 pressure and allows for the calibration of its air flow rate. The calibrated flow rate will be maintained at a constant flow throughout the collection period. Four timing routines are selectable from the keypad and continuous flow is achieved by pressing the ON key for 4 seconds. The OFF key manually stops the pump from sampling.
