Introduction：

       Nowadays, living standards are getting better and better. People have paid more and more attention to the health and fitness in addition to eating and drinking; and more and more people are choosing oxygenerators as the gifts for family members during the Spring Festival and other holidays. The oxygenerator can improve the living quality of people suffering from dyspnea caused by pneumoconiosis and impaired lung functions by other reasons. SinOne noncontact water level detection technology has provided the excellent solution by wetting oxygen in humidified tank to avoid it from being too dry.
