PROSYS INTRODUCES PORTABLE PDA CONTROL FOR THE MegaSonic AND UltraSonic CAVITATION METROLOGY PROBES

The ProSys Cavitation Sensing Metrology Probes took a leap in technology with the introduction of a PDA control system that allows the Probes to be fully portable. The PDA control utilizes proprietary software that enables the engineer and researcher to gather data in the production environment.

San Francisco, CA July 12, 2004 - ProSys Inc., the leader in advancing Megasonic transducer technology and products, today unveiled the ProSys MicroPDA Controller for the Cavitation Probe line of Metrology products.

"With the need to measure actual Sonoluminescence Cavitation output in the cleaning baths, the Metrology Probe needed to be fully portable and clean room compatible. While lab work has proven the need for Cavitation uniformity, a tool like the MicroProbe is essential to monitor the actual production cleaning processes." said Mark Beck, Founder and CEO of ProSys. "Detecting and monitoring Cavitation density and uniformity will be a key to reducing fine structure damage."
