An airway humidity sensor incorporating a small, dry thermocouple and small, wet thermocouple to measure cyclical humidity in inspiration and expiration by the psychrometric principle, the psychrometric component incorporating dialysis micro-tubing in contact with the wet-bulb thermocouple junction, the thermocouples being offset from one another across the cross-sectional plane of the airway in a direction normal to the airflow. |
