Recently launched at Analytica in Munich, the new expert measuring device for foam analysis.
The RMFA integrates the standardized vessels according to ASTM D 1173 in a newly developed measuring device for electronic foam height measurement.
An LED bar and a sensor bar are fitted along the intake vessel which allows the foam height to be detected based on the difference in brightness at the foam-air boundary, a measuring method which KRÜSS also uses successfully in the Dynamic Foam Analyzer – DFA100.
The electronic height detection ensures considerably improved repeatability of the measurement and, with a resolution of 0.4 mm, achieves a previously unattainable precision. The initial foam height measurement does not have to be manually coordinated with the discharge of the reservoir solution. Instead, it corresponds to the electronically detected time at which the maximum foam height is registered. The other measurement times are also adhered to exactly. As well as the foam height, the instrument also records the height of the liquid. In this way, the raw data document whether the filling level specified in the norm has been accurately maintained.
Repeatable measurements – electronically and exactly to the norm.
As well as improved reproducibility and accuracy, electronic data measurement also saves a great deal of time, as the measurement no longer has to be followed live. The user therefore gains five minutes with every foam analysis, which he can use to prepare the next surfactant solution, for example.
