Spirometer for PowerLab

Spirometer for PowerLab

The FE141 Spirometer is a precision differential pressure amplifier for measurements of respiratory flow rates with a respiratory flow head. The Spirometry Extension add-on software for LabChart allows flow, volume and forced expiratory measurements to be calculated. By selecting a suitably sized flow head, the Spirometer can be used with small animals such as mice or rats through to large animals and humans. Applications include differential pressure, airflow and breathing measurements.

  • Precision differential pressure input that can be used to determine flow rates by suitable flow head selection
  • Provides additional amplification required to deal with a variety of flow rates, from fractions of a liter per minute (mice and rats) to a thousand liters per minute (adult humans during exercise)
  • Additional programmable filtering to remove unwanted signal frequencies
  • Software controlled zeroing for offset removal
