|K43002 Foaming Characteristics Apparatus & Data Acquisition Software|
Foaming of lubricating oils in applications involving turbulence, high speed gearing or high volume pumping can cause inadequate lubrication, cavitation, overflow and premature oxidation. The sample is blown with a controlled volume of air at different specified temperatures, including a newer high temperature test at 150°C. The resultant foam is measured at the end of each aeration period and at different intervals afterward. In the high temperature test, the amount of time required for the foam to collapse to 0 after the aeration period is also measured.
Features and Benefits
Dual-twin models for standard foaming characteristics tests
High temperature liquid baths for Sequence IV tests
Automatic time sequence models for both tests
Custom configurations for specialized applications

|K43002 Foaming Characteristics Apparatus|
|Performs two tests at 75°F (24°C) and two tests at 200°F (93.5°C). Consists of two 12x18" (30.5x45.7cm) constant temperature baths with 1000mL test cylinders, certified diffusers, air delivery tubes, and flowmeters (94mL/min.) for each sample. Baths are equipped with microprocessor temperature controls, copper immersion heaters and 1/20hp circulation stirrers to maintain temperature uniformity of ±1°F (±0.5°C). Microprocessor PID control provides quick temperature stabilization without overshoot and the bath is protected by an overtemperature control circuit that interrupts power should bath temperature exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature values in °C/°F format. Test cylinders are held securely in place by quick-locking cams in the bath cover assembly. A separate stainless steel support rack is provided to hold the test cylinders after removal from the bath. Cold bath (24°C) has built-in coils for circulating exit air from the high temperature test cylinders prior to passing to a volume meter, and a separate coil for circulating cooling water or refrigerant when the ambient temperature exceeds the test temperature. Supplied with rubber stoppers and glass air outlet tubes for each cylinder. Bath controls are enclosed in a finished steel base with chemical resistant polyurethane enamel finish. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information.

|K43000-SFW Foaming Characteristics Software|
|Foaming Characteristics "test intelligent" software simplifies the testing process by providing sequential test prompts for assisting the operator with each step of the test procedure, and provides timing for both the foaming test and foam settling for up to 4 samples simultaneously. The sophisticated Windows®-based software package features an easy-to-navigate operation, a straightforward user interface, minimal draw on Windows® memory resources, automatic real-time data acquisition via RS232 connection, and a timer / stopwatch feature for general laboratory use. The active zoom, pan, and trace feature allows the ability to change axes and the magnification of any graph sector to view data in greater detail. The final test data is exported with graphs and test parameters (user name, sample name, sample ID, test type) either directly to Microsoft® Excel, in ASCII file format for use with LIMS or any other spreadsheet programs, or directly to a printer with a test report according to ISO guidelines. Test data is saved in a database format for determining test averages, standard deviations, and ASTM test repeatability. The software package requires no PC hardware installation and includes the software installation CD and computer connection cables.
