The UOL Handheld Series is a microprocessor-based instrument that provides continuous monitoring and detection of ultrasonic frequency (in kHz) and reference energy (in mVrms - voltage root mean square) in a liquid medium of a ultrasonic cleaning bath. It employed a handheld probe made of 316 L stainless steel to collect data at random points. With the reliable data collected, one can made a good judgment of performance of the ultrasonic tank over a period of time.
