In ultrasonic cleaning, it is very important that the ultrasonic cleaner is working properly. Using a malfunctioning cleaner is a waste of time and resources because the cleaning is inefficient.
There are ways to know if an ultrasonic cleaner is not defective. Some of the ways can be done by just about anyone while others require technical skills to be performed. The easiest ways to check the performance of a cleaner are to do the microscope slide and foil tests. These tests can be done by anyone who has the needed items.
For people with technical skills, testing the parts of the cleaner can be done. The parts that should be checked are the generator and the transducer. Know if the power inputted to and outputted by the ultrasonic generator is correct. See also if the transducer’s capacitance and resistance are appropriate.
