Measuring instrument for the cleaning efficiency of ultrasonic baths in operation

Ultrasonic cleaning baths are used for many applications – both for industrial and for domestic use. PTB has developed a new measurement procedure which allows the cleaning efficiency of such ultrasonic baths to be determined objectively for the first time. Hereby, a defined quantity of impurity is applied onto an oscillating quartz crystal; the quantity abraded is determined using a new measurement principle. This simple procedure, which has been developed at PTB and can be standardized, can be used directly in operating ultrasonic baths and serves the purposes of quality assurance, e. g., in medical engineering.
