pb-500 Ultrasonic Meter, 0 to 500 kHz

Measures both cavitation energy and frequency in your ultrasonic tanks, which allow you to:

¨ measure your cleaning tank performance
¨ set your tank energy level
¨ establish tank to tank uniformity
¨ map the energy variations in your tank


The Ultrasonic Energy Meters (0 to 500 kHz) are precise instruments for measuring ultrasonic and cavitation energy density, as well as the ultrasonic frequency. The systems measure energy density at a given point in time and space in a single fixed direction in the tank.

The ultrasonic meters are simple and easy to use yet contains sophisticated electronics for data storage, retrieval and analysis. Readings are processed 1.5 times per second for fast accurate display on the front panel LCD.

In "auto mode" the unit will gather statistical parameters including average, standard deviation, minimum and maximum readings. 

This allows you to establish several strategies to characterize a tank. Data collection strategies include:

• Measuring energy variations at a given point in the tank as a function of time.

• Mapping a tank by ‘walking’ the probe at a fixed depth under the surface of the tank.  Click HERE to see an example figure.

• Comparing average energy from tank to tank, over the life of a tank, or unloaded versus loaded with parts to be cleaned.
