Since 1996, ppb has been the leader in providing solutions to your Ultrasonic and Megasonic cleaning efficiency concerns. With ever decreasing dimensions and the utilization of 300-mm wafers, the understanding and analysis of your cleaners has never been more critical.

Our advanced line of cavitation metrology instruments have been proven to increase yield by accurately measuring the energy and frequency in Ultrasonic and Megasonic cleaning baths, nozzle streams and films, and single wafer cleaners.

Our digital hand-held meters allow users to map the in-situ energy distribution, establish tank-to-tank uniformity, and identify de-bonded or failed transducers. This is accomplished through our advance sensor and signal processing design, which captures the cavitation implosion and the driving acoustic signatures.

Our probes provide an accurate and repeatable measure that incorporates such solution variables as temperature, vapor pressure, surface tension, and flow rate. Continuous monitoring is also possible with our Monitoring-Transmitter. NIST Traceable Calibration available.
