AccuFlo™ Digital Turbine

The AccuFlo™ bidirectional turbine with optoelectronic rotary sensor is easily detached for cleaning. Sapphire bearings ensure optimal performance for the life of the turbine. AccuFlo has a unique flow trigger algorithm that allows tidal breathing prior to the patient expiratory effort making the spirometry test easier for the patient and insuring quality test results.

AstraPro™ Software

Choose either Pre- and Post-bronchodilator and bronchial challenge testing or use the incentive program with your pediatric patients or adults. The Astra BT communicates with AstraPro wirelessly via Bluetooth.
