Ultrasonic Cleaning Indicator CDWU

SKU: CDWU Category:



Ultrasonic Cleaning Indicator for ultrasonic cavitation performance test

Applicable regulations: .
Exposure conditions: . Units per box: .

Chemdye® CDWU indicator was designed to monitor the cavitation process. It
allows testing the operation of ultrasonic washing machines with different
washing configurations by measuring the generated cavitation energy. CDWU
indicator consists of a clear vial, with a reactive blue-colored solution and glass
beads immersed in it. When the cavitation energy is adequate, vibration of the
glass pearls triggers a color change in the solution, from blue to yellow, through
a range of green color intermediates.
