The handheld PG meters by Glottal Enterprises estimate lung pressure (subglottal pressure) using the proven interpolation technique developed by Glottal Enterprises founder Martin Rothenberg, and employed in the Aeroview system. However, unlike Aeroview, the PG units provide a real-time meter indication of the estimated lung pressure. There are two models, the PG-20, for lung pressures up to 20 cm H2O, and the PG-100, for pressures up to 100 cm H20, as may be found in singers.
