BF-II
Electronics Spirometer
Ⅰ.Brief Introduction
Electronics spirometer is a high-performance lung testing instrument. Adopting the winged gas flow sensor, matched with low consumption and high effective microprocessing system and precision electronic-circuit, this instrument operations steadily, sensitively and accurately. It can be used widely in health and medical treatment.
