How is ultrasonic foil test done
Get a stick and aluminum foil. Cut three 4” x 8” pieces of foil and then fold all three pieces over the stick. Fill the cleaner’s tank with cleaning solution. Degas the solution and increase its temperature. Dip the ends of the foil into the solution. One piece of foil should be positioned in the tanks center while each of the other two pieces should be positioned near the walls of the tank. Let the ultrasonic cleaner run for ten to twelve minutes. When the time is up, get the stick and inspect the three pieces of foil. If there is no problem with your cleaner’s cavitation, each piece of foil should have wrinkles and small holes. The level of winkles in the three pieces should be almost the same.
