• The portable pulmonary function measurement instrument can be used to measure:

• Adopting pressure-flow sensor, sensitive, precise, easy to launder, clean and durable

• All parameters can be displayed on large screen(320 x 240),
•  Built-in memory can store maximum 300 cases of patient measurement results

• The instrument can calibrate automatically, all English operation, more convenient to operate

 

• 110mm thermal printer built-in, can print out a clear clinical report, predicted value, measured value

 

•    VC time 50 seconds, 
•    FVC measuring time 25 seconds, 
•    MVV time 12 seconds, in favor of the coordination between patients and the device

• Compact and flexible
