HCT-series Cleaning Tank Hydrophone

A hydrophone to characterize ultrasonic cleaners

Despite the wide adoption of ultrasonic and megasonic cleaning, the acoustic characteristics are not well understood.  The HCT hydrophone with MCT acoustic meter bridges this gap, offering a reliable solution to characterize and monitor the acoustic properties of ultrasonic and megasonic cleaners.   Its unique single point sensing design allows measurements with high spatial resolution to offer true 3-dimensional mapping of the cleaning tank.  The rugged construction allows routine mapping of the acoustic pressure and ultimately determination of the cleaning efficiency of the tank.
