Measuring foam formation and decay speed for quality control - reliably and reproducibly
- Data sheet
Foam is a welcome companion to many products, but almost as often it is a nuisance that must to be avoided. Either way, for quality control of your products and processes, it is necessary to exactly determine the foaming behavior of the liquids and foam-inhibiting additives involved. The easy-to-use Foam Tester – FT carries out this task reliably and in an exactly repeatable manner. Using accurately controlled gas flow and precise electronic foam height measurement, the Foam Tester gives you significant results for the foaming capacity of your liquid and the decay speed of the resulting foam.

Maximum foam volume and height
Decay curves: total height and volume as well as foam and liquid height and volume at each measured point in time
Time values for the reduction of liquid volume in foam and foam volume to 50% (foam half-life)
Comprehensive and automatic assessment of the quality of foam-forming liquids
Having full control over the foaming behavior of a liquid requires reliable foam tests. However, many of the devices and test procedures available involve user-dependent foam formation methods and result readings, which makes it hard to optimize foam formation and prevention based on solid numbers. The Foam Tester is designed to fill this gap. It provides for standardized foam formation by electronically controlled gas flow and for objective result reading thanks to precise, electronic foam height measurement. The measurement is carried out automatically and user-independent using intuitive and easily adaptable automation programs.
By recording the total height of foam inside the measuring column and the liquid height beneath the foam, data are related to the absolute amount of foam and also give conclusive results for the liquid content and flow-out speed (drainage). All in all, the Foam Tester provides the key results for assessing the quality of the foam-forming liquid.
Specially designed to test foam prevention capabilities of liquids and additives
In many products and processes, such as cooling lubricants or spray painting, foam formation can directly affect quality. Even unstable foams are a problem when the liquid is in permanent motion and foam is created faster than it decays. Quality control for such liquids and the defoamers/antifoamers involved requires an instrument that captures the formation and stability of foam even if it breaks down quickly. The Foam Tester does this job by recording the decay curve with a particularly high data rate. Moreover, automated cycles can reveal whether the foam level decays fast enough or rises from measurement to measurement.
To adapt the measuring conditions to the real process, measurements can be carried out temperature-controlled at up to 90 °C or with externally connected gases such as carbon dioxide.
Impressively easy to use
The ease of using the Foam Tester when preparing the measurement and when cleaning is of great advantage. The measuring cylinder is placed in the instrument with a single movement using the plug-in unit. The flexible system, which simply uses paper filters for foaming up, enables all components to be cleaned quickly. It also even allows one sample to be prepared while another measurement is running. This means more measurements in the same time.
Moreover, clear data management with the instrument’s ADVANCE software ensures gapless documentation of raw data and end results, thus completing the Foam Tester’s suitability for quality control.
