Assuring the Cleaning Effectiveness of Megasonic
Doris Schulz

Monitoring frequency and power is an important quality assurance tool in ultrasonic cleaning applications in the range of 250 to 2,000 kHz. A provider of industrial parts cleaning systems has now demonstrated that laser acoustic microphones can also be used to reliably detect sound waves in the high-frequency range up to 2 MHz. Based on this, the company has expanded its measurement solutions.
