Every Mini Wright AFS peak flow meter is individually assembled and calibrated by highly trained operatives to ensure consistent performance and accurate readings which can be transferred on to an asthma peak flow chart. All calibration test equipment is frequently checked to ensure that the highest of standards are met. The scales cover 30-400 L/min.
Each Mini Wright AFS peak flow meter is manufactured to one of two standards; the EU and ATS.
Peak flow requires a forceful exhalation and to encourage young children to do this, the Windmill trainer is an incentive challenge. By moving the Windmill further from the mouth more exhalation force is required to turn it.
