Terragene Washing Control – Ultrasonic Cavitation

Indicators for cavitation performance testing Ultrasonic Washers

Terragene Chemdye CDWU indicator consists of a transparent vial, with a blue-coloured re-active solution and glass beads immersed in the vial.
During cavitation, vibration of the glass pearls trigger a colour change in the solution from blue to yellow, through a range of green intermediate colours.
When cavitation energy is high enough to guarantee a correct washing of the instruments, the final result of Terragene’s Chemdye CDWU vial will be a yellow colouration.
A greenish result, indicates a weak cavitation zone, located in that area of the ultrasonic washer.
Terragene Chemdye CDWU indicators are suitable for ultrasonic cleaners operating at frequencies > 35 kHz, between 18-70°C
Terragene Chemdye CDWU indicators are designed to monitor the ultrasonic machine WITHOUT LOAD, in order to detect strong and weak spots of cavitation.
