There are several methods available to you which can test the day to day functions of your ultrasonic cleaner. You will want to keep in mind that temperature and solution concentration can have a huge effect on the operation of your unit. If you are going to use these methods, you must perform several tests and take a look at the average data. It is important to take into consideration the variances in temperature and solution.
The Ultrasonic Cleaner Foil Test
This is by far the simplest test you can perform, but it is also the most susceptible to temperature and solution conditions. When running this test, make sure your solution concentration and water temperature are as close as possible to each other. Make sure to perform testing before your first use of the day.
Take a piece of regular store bought aluminum foil. Cut it to be the size of the inside of wall of your cleaning unit. Suspend the foil in your cleaning solution making sure that the foil does not touch the bottom of the unit. Touching the bottom of the unit can ruin your results. Turn the unit on and allow it to run for approximately thirty seconds or so.
The results of the test should be a uniform set of holes or punctures in the aluminum foil. The holes should be small, 1-4mm, and should be approximately the same size. A non-uniform pattern means a malfunction and adjustment is needed.
Graphite on Ceramic Test
Another testing method uses a ceramic disk with graphite on it. Pencil can work, as can other types of graphite powder. This test is performed by taking the disk and placing it into the cleaner to see if it comes out clean.
There are some drawbacks to this method. Only a small part of the tank is tested when employing it. Experts recommend the foil test over this graphite on ceramic option.
Testing Ultrasonic Cleaner Generator and Transducers
If you or your staff are technically or electrically handy, this might be a method you can use. Take measurements of the power output of your generator as well as the power inputs on your transducers. See if the measurements match up with the specifications provided by the manufacture of your ultrasonic cleaning device.
Cavitation Meter
The most direct method is to use a cavitation meter. This is a portable device that is used to measure the sound wave performance inside of your cleaner.
While any of the above testing methods for your ultrasonic cleaner can be effective, remember to check the performance of your ultrasonic cleaner on a regular basis. Proper testing will ensure that your ultrasonic cleaner is performing in tip top shape.
