Exhalation Pressure Transducer
An exhalation pressure transducer is present in the analyzer for use with the
Accurate NO breath kit and for detection of exhalations during breath-by-breath
measurements.
Thermal Mass Flow Meter
On-line measurement of exhalation flow rates can be performed using a optional
flow meter. The signal from the flow meter is included in the RS-232 output.
