L/min: Dry air at 77° F (25° C) and 14.7 psig barometric pressure.
* Includes ± 1% for linearity and hysteresis with no zero drift for the pressure transducer and ± 2 % for temperature and
humidity variations.
The sensor must be corrected for barometric pressure, and oxygen concentration.
** Frequency Response is signal attenuation to 0.707 input and assumes 100 Hz sample rate.
