Avoid disaster with an ultrasonic performance test

In the world of ultrasonic cleaning not all ultrasonic cleaners were created equally. In fact performance varies across the ultrasonic manufactures and their ultrasonic cleaner product range.

Many other Brands of ultrasonic cleaners fail the ultrasonic performance test from day one of their working life. Unfortunately it is better to discover the inefficiency sooner rather than later and to minimise further losses and litigation through poor ultrasonic cleaning.

The importance of the ultrasonic performance tests, as recommended by Standards Australia. Has a twofold benefit to the consumer.

1. You will know your ultrasonic cleaner is cleaning through the whole tank and not just in sections of the tank.

2. The ultrasonic cleaner should be serviced if it is not passing the performance test and so you reduce the future down time of the cleaner scheduling in a service now rather than later when the machine is more damaged.

The risk of incomplete sterilisation is high if medical instruments are not completely cleaned in the ultrasonic cleaner, because the ultrasonic cleaner is not cleaning through the whole tank as it should. This could lead to the sterilization process failing and cross contamination infection between patients.

In the case of ultrasonic cleaning of parts or circuit boards, preparing for the next process like, varnishing. The ultra-sonic cleaner must clean through the whole tank or you run the risk of the next step with the part or circuit board failing. A circuit board only partially ultrasonically cleaned of flux after a repair or creation could be subjected to arcing on the dirty sections causing damage.

Also if you are cleaning parts before a final paint, the paint may not adhere properly to a dirty surface.

The minimum amount of times the ultrasonic performance test should be performed on your ultrasonic cleaner is when you first purchase, so you know what to expect and that the ultra-sonic cleaner is functioning correctly. If you notice any change in the length of time needed to clean parts or if the ultrasonic cleaner changes in any way, a performance test should be performed on the ultrasonic cleaner before the warranty expires. Many companies like hospitals perform more regular ultrasonic performance tests limiting increased risk and ramifications.

Various ways of doing performance tests are available. "Standards Australia" recommends the foil or graphite on disk test. Most tests only test small sections of the tank. Therefore "Unisonics" recommends using the foil test because the test checks the whole tank for cavitations. The process is quick, simple and effective.
