The Ross Miles Foam Analyzer – RMFA from KRÜSS is the world’s first instrument for automatic measurements of foamability and foam stability in accordance with ASTM D 1173. The RMFA uses standardized vessels in a newly-developed measuring set-up for electronic, optical foam height detection. Measuring the initial foam height does not have to be coordinated with the discharge of the reservoir solution anymore, but is registered electronically. Thanks to narrowly observed measuring times as per Ross-Miles of one, three, and five minutes and a height resolution of 0.4 mm, analyses in accordance with ASTM D 1173 achieve precision that was previously unheard of.

The quality of the analysis also no longer depends on the care that is taken by the user when reading the foam height. This has increased the repeat accuracy considerably. The electronic data measurement also saves a great deal of time, since 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 sample, for instance.
