25mm (black rubber ring, 1.7MHZ for humidifier)

This nsducer is mainly used in household humidifiers, the specification is 25mm in diameter (refer to the size of the r sheet measured by removing the apron, plus the apron 30mm, please measure the size before buying) the frequency is 1.7MHZ Front surface Titanium plated. Anti-, corrosion-resistant and ble.

Precautions:

1. Please do not turn the r upside down after connecting the power, it will damage the r.

2. Please ensure that the running time does not exceed 10 hours per day.

3. When the r is running, please do not touch the sheet.

4. To ensure the water quality, please use clean tap water. (The deterioration of water quality will affect the service life)

5. Please cut off the power before moving or repairing.

6. The sheet is a consumable item, and its service life is about 5000 hours. If you find that the amount of mist produced by the r is significantly reduced, please use a cotton swab to clean the sheet (without any detergent) to keep the sheet clean. If you find that the amount of atomization is still very small after cleaning, please rep a piece.
