Here's the translation of the ultrasonic humidifier series information from Chinese to English:

**Ultrasonic Humidifier Series**

**I. Working Principle of Ultrasonic Humidifier**

Ultrasonic humidifiers use electronic high-frequency vibration (with a vibration frequency of 1.7MHz). Through the high-frequency resonance of the atomizing plate, water is thrown off the surface to create naturally drifting water mist. Without the need for heating or chemicals, they produce 1-5 micrometer water particles that float in the air, thereby increasing the relative humidity of the air.

**II. Operating Conditions for Ultrasonic Humidifier**

1. Ambient Temperature: The normal operating temperature range is 0-40°C.
2. Water Source: Clean neutral tap water should be used.

**III. Features of Ultrasonic Humidifier**

- Uses an integrated atomization module with replaceable chips for easy and simple maintenance that can be performed on-site.
- High humidification efficiency (nearly 100%), with strong humidification intensity. It produces small and uniform mist particles that can quickly achieve the desired relative humidity.
- The integrated atomizing core has a built-in water protection device that effectively ensures the atomizing core stops working automatically when the water level is too low, eliminating the need for additional equipment and saving costs.
- Flexible and convenient control methods with fully automatic humidity control.
- Digital automatic humidity control with an imported humidity sensor for high control precision and quick response. It operates continuously after setting without the need for constant monitoring.
- Made with a stainless steel casing that is aesthetically pleasing, corrosion-resistant, and has a long lifespan.
- Equipped with high-performance automatic water supply solenoid valves, overflow outlets, and drainage outlets, making it easy to use and safe and reliable.
- After extensive testing and years of practical detection, the structure is compact and reasonably matched. It operates noiselessly and has high atomization efficiency for liquids.
