title: Accuracy of hydrostatic pressure measurement with a disposable dome transducer system.
abstract: The Gould-Statham P23id transducer with disposable dome was tested for accuracy between 0 and 20 mm Hg. With a criterion of +/- 2 mm Hg, 16 per cent of 74 systems failed. Inaccuracies were relatively large (SD, 6.02 mm Hg). The source of the unreliable measurements was poor sealing between the membrane of the disposable dome and the transducer diaphragm.
