The accuracy of electronic humidifiers depends primarily on the integrated type of sensor; the capacitive type are ...

Although the humidifying capacity of a bubble respiratory gas humidifier is rather low, it may be improved by increasing the water temperature. A bubble bottle is mostly used in oxygen therapy with high flow rates via a mask, nasopharyngeal catheter, or nasal cannula in order to prevent drying of the mucous membranes in the nose and mouth.
A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor.
