Artificial ventilation test lung PWG-33

for general care

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 User defined waveforms Sinus waveforms Square waveforms Trapezoid waveforms Reproduction of any waveform defined by user Main features: All parameters of generated waveforms are fully traceable to National Standards All generated curves can be proportionally scaled Full automatic measurement of flow meter’s resistance Full support of human differential tests, according to ATS Evaluation of test results and error analysis, according to ATS Full automatic test sequence definable by the user Technical data Maximal volume 10.00 liter Maximal flow rate 20.00 liter/s Minimal rise time to flow rate16.00 l/s @ back-pressure 3kPa 4.00 ms Maximal slew rate to flow rate16.00 l/s @ back-pressure 3kPa 4000 l/s2 Maximal back-pressure of the flow sensor under test 4.00 kPa @ 12 l/s Volume resolution 0.3829 ml Volume accuracy 0.2 % or 10 ml which ever is larger Flow accuracy 0.5 % or 25 ml/s which ever is larger Time accuracy 0.2 % or 5 ms which ever is larger BTPS simulation (BT - option): Temperature of expired air 37°C ± 2 °C (adjustable by the user) BTPS simulation (BT - option): Relative humidity of expired air 92 % ± 5 %
