Foaming Characteristics Tester is a benchtop unit and offers ambient to 100°C temperature range with precision of ± 0.1°C. The instrument is distributed into two groups of baths at 24°C and 93.5°C and separate control for temperature as well as flow rate. Equipped with gas diffusion head, oil-free air pump and air filter. Allows determination of the foaming characteristics of lubricating oils at specific temperatures by empirically rating the foaming tendency and the foam stability.
