BS45F3843 Description
The BS45F3843 is a device dedicated for use in ultrasonic atomiser applications. The application principle for ultrasonic nebulisers is to use electronic high-frequency oscillation and ceramic nebulising chip high-frequency resonance to break up the liquid water molecules thus generating a fine mist without requiring heating or any chemical substances. pared with the heating nebulisation method, the ultrasonic...
