Piston - Model PWG-33 and PWG-33BT -Pulmonary Waveform Generator
FromPiston Medical
Pulmonary waveform generator is the most essential equipment for developing and testing spirometers and other flow/volume measuring devices. PWG-33 is the ideal test equipment for R&D companies, for manufacturers and for authorized test laboratories as well. PWG-33 has incomparable accuracy and fidelity in generating waveforms. PWG-33 provides the highest peakflow with the fastest acceleration it is the real market leader in all aspects. PWG-33BT provides full BTPS simulation for all types of exhaled curves
