SleepSense Disposable Flow Sensors share these advantages:
Comprised of many thermocouple elements, the Respiration Flow Sensor
produces a signal proportional to respiratory air temperature changes. The
signal generated provides a clear, reliable indication of respiration airflow.
These sensors are used with the 1415V2 Interface Cable, or with the 1410
cable outside the USA. The output may be connected to any AC (low level)
channel on the recorder.
