wedge spirometer
A waterless spirometer constructed of two large rectangular plates with edges connected by accordion-pleated rubber so that large changes in volume are accommodated by small changes in the acute angle of the wedge-shaped interior, sensed by an electrical transducer; designed for rapid response by reducing the acceleration of the moving parts.
