Sonic Meter…Ultrasonic Cavitation Intensity Instruments

We offer the most reliable ultrasonic instruments for quantifying and calibrating the intensity output of ultrasonic cavitation cleaning tanks.

The Sonic Meter measures the ultrasonic scrub-force intensity per unit area in pressure.  It uses a piezo sensing element that directly correlates the average pressure at a specific location.  The slender 8mm probe is ideal for tank mapping arrays of points at multiple levels in the z direction.  At each point it can average readings.  The total average of readings along with the mapped points will provide the user with the capability to…

  • Detect energy loss
  • Compare tank to tank output
  • Determine most efficient location to place parts
  • Map and calibrate intensity over the entire tank volume

Ease of use…

The Sonic Meter uses a simple LCD display with inputs from a four button membrane keypad.  There are three windows to select from.  The meter’s precision machined, handheld housing with simple to use inputs and LCD display is the ideal user interface for both engineers and technicians.  The user will be measuring and mapping the intensity of their tanks within a few minutes.  Our continued product refinement has made Sonic Meter the industry leader for calibrating the output of ultrasonic cleaning tanks.


Our meter/probe and the user interface are built with superior standards for use in industrial applications where reliability is paramount.

Our hermetically sealed, full stainless steel probe is designed and built to withstand harsh/corrosive solvents and fumes.  An all too common problem with cavitation/energy meters is the cracking of the probe’s plastic housing and seals after exposure to harsh solvents, thus leading to faulty measurements and eventual failure.

We do not use seals or plastic parts in the construction of our probe.  Our probe housing is constructed entirely of stainless steel with a brazed ceramic connector, and is hermetically sealed at both ends through laser welding.  By sealing both ends, we avoid the common issues from both the bath’s solvent and the out-gassed fumes, which can seep into the probe’s connector or tethered line junction.


Because of our solid reputation and commitment to our customers, Sonic Meter cavitation instruments are used throughout the world as indispensable tools for maintaining vital process control in high precision component manufacturing.  Our meters are CE and NIST certified and are supplied with data-test and certification sheets.  All NIST traceable calibrations are controlled and maintained exclusively by Sonic Meter.

Sonic AO

The Sonic AO is designed specifically for quantifying the high intensity cleaning forces (scrub-force per unit area) output by the most commonly used ultrasonic tanks cleaners.  With a wide bandwidth from a thousand Hertz up to 500 kHz output, our meter is compatible with most commercial tanks.  To view more on the specifications, click Specifications.

Manufactured and serviced in USA.
