Automatic sampling unit

for repeated testing to obtain statistically assured test results.

Double walled sampling vessel

allows exact adjustment of the sample temperature. This is done by controlling the thermostat using a temperature sensor inside the sample liquid.

Rotor for foam generation

The patented rotor allows one to adjust the air-intake into the sample liquid allowing reproducible foam generation. At the beginning of this test it is possible to thoroughly mix the sample without generating foam.

Sensor unit with needle detectors

to precisely determine the foam volume by measuring the surface profile of the foam.

The measurement of the foam height and, therefore, the measurement of the foam volume, is done by a patented sensor technology which can determine foam generation and foam disintegration. Situated at several positions, the needle detectors identify the "foam hill" enabling the device to calculate a surface profile. Thus, it is possible to precisely evaluate the foam volume.
