Model No. SPM 100


Technical Features

  • Max Volume: 10L
  • Flow Range : 1L/s~16L/s
  • Volumeaccuracy: ±3% or 0.05L [Whichever is greater]
  • Flowaccuracy: ±10% or 0.3L/s [Whichever is greater]
  • The highest resistance to flow within the measurement is 6Pa/L/s,and this resistance may be occur at 14L/s

Product Description

  • Forced Vital Capacity [FVC], Forced Expired Volume in one second [FEV], the ratio of FEV1 and FVC [FEV1%]. Peak expiratory flow (PEF), 25% flow of the FVC [FEF25], 75% flow of the FVC [FRF751 and average flow between 25% & 75% of the FVC [FRF75] can be measured. Besides, the testee condition can be shown by the ratio of the measured value and the predicted value.
