Checking the performance and quality of the ultrasonic cleaning device:
The aluminum foil test is a simple and widespread method used to check the efficiency of an ultrasonic bath.
To perform the aluminum foil test, follow these steps:
Prepare the ultrasonic bath:
Fill the ultrasonic bath tank with water and after degassing, turn on the device to the desired settings for your cleaning program. It is important to make sure that the ultrasonic bath is functioning properly and is adjusted to its normal parameters.
Take a piece of aluminum foil:
It is important to note that the thickness of the foil should be selected based on the specific frequency of the ultrasonic bath and the desired sensitivity in the aluminum foil test. As a general guide, foil thicknesses in the range of 25-50 microns are typically used for most ultrasonic baths.
Then place the aluminum foil in the ultrasonic bath and make sure it is completely submerged in the water. Make sure that the foil does not touch the walls or bottom of the tank so as not to interfere with the test.
Run an ultrasonic bath:
Allow the ultrasonic bath to run for a certain amount of time, usually about 1-2 minutes. This period of time gives the foil time to react to the pressure effect of the ultrasonic waves
Check out the aluminum foil:
After the specified time, remove the aluminum foil from the ultrasonic bath. Check the surface of the aluminum foil for small holes, tears, or other signs of damage. If the ultrasonic bath is working properly, you should see small holes or cracks on the surface of the foil. These holes are formed due to the pressure effect of the intense ultrasonic waves produced by the ultrasonic waves.
The aluminum foil test is a qualitative assessment of the performance of the ultrasonic bath and provides a quick indication of whether the unit is generating enough pressure to produce ultrasonic waves for cleaning purposes. If the foil shows little or no signs of damage, it may indicate that the ultrasonic bath is not working properly and its cleaning efficiency may be compromised.
