Digital Peak Flow Meter for Asthma and COPD Lung Performance Measure Peak Expiratory Flow and Forced

Function Description
MSA100 Peak Flow Meter is a hand-held pulmonary function measuring medical device that measures your
maximum possible exhalation which is called peak expiratory flow (PEF) and forced expiratory volume in
1 second (FEV1). The accuracy meets American Thoracic Society (ATS) Standard 2005 Revision.
MSA100 is suitable for children through adults who are capable of following the instructions for use. Because
the Meter has an automatic memory three hundreds readings, you can take the Meter with you the next
time you visit your doctor for a review of many readings. The doctor makes an appropriate treatment plan
based on them, and helps patients to recuperate health.
MSA 100 Peak Flow Meter supports USB connection. When measurement records add up to maximum volume,
you can transfer the records to PC via USB. Then using software to help save and track for long term.
TECHNICAL SPECIFICATION
MSA100 Peak Flow Meter is a hand hold pulmonary function measuring medical device that measures your
maximum possible exhalation which is called peak expiratory flow (PEF) and forced expiratory volume in
1 second (FEV1). The parameters are displayed on the LCD screen. MSA100 also can record
measurements up to 300 pieces, and supports USB connection. When measurement records add up to
maximum or other patient would use, you can transfer the records to PC via USB, then a software help to
save and track for long time.
