25mm Ultrasonic Humidifier Film Plate Ceramic Atomizer Mist Maker Piezoelectric Transducer Humidifier Accessories 1.70MHz D25mm Atomized Transducer: It uses the principle of ultrasound to turn water into tiny water droplets into a mist. It is widely used in the adjustment of dry humidity in hotels, bonsais, and homes to prevent air drying from affecting health. The atomizing tablet can not be directly connected to the electricity, it needs to be used on the control panel to spray. . Specification size: 25x1.2mm Resonance frequency: 1.70MHz Resonance impedance: 52% Static capacitance: 1800pF Atomization volume: 380ml / h This atomizing sheet is suitable for high-power atomizing plate and the diameter of the atomizing sheet is 25mm. Note: The diameter of 25mm refers to the size of the apron removed. When you measure it, be sure to remove the size of the apron outside. The reason why the humidifier does not spray is not only the reason of the atomizing film, but also the failure of other electronic components will cause the non- spraying. _x000D_
