Abstract:
A foam detector apparatus for detecting the foaminess of a sample, the apparatus comprising:a) a test sample container for containing the test sample; b) heater means for heating the test sample in said sample container, said test sample having a tempering temperature; c) temperature measurement means for measuring the test sample temperature; and d) foam detector means for detecting the presence of foaming in the test sample, said foam detector means comprising a detector probe placed above the sample surface, said detector probe having a measuring surface comprised of a low thermal mass material, a heater means for heating said measuring surface to a temperature above the test sample tempering temperature and a temperature measuring means for substantially continuously measuring the temperature of said measuring surface, wherein said detector probe indicates the presence of foam when said foam contacts said measuring surface, thereby cooling said measuring surface.
