Automatic controller, upgrade, same as FM-9 but specifically to upgrade owners of Lawler Model All key parameters are displayed during the test. However, the manometer is replaced by a high precision digital pressure controller. Once you start a programme you can leave the Autowash unattended and the instrument sounds an audible warning when the cycle has finished.
Long temperature probes are provided for each of the 4 test positions for digital control and test sample temperature display and precise temperature control during the foaming process.
Even low levels 1 ppm and above of silicone contamination interfere with test results. Automatic controller, upgrade incl. The automated pressure ramping profile generates the Dynamic Bubble Point pressure that is used to determine Pore Diameter of stainless steel and ceramic diffusers.
An automated, two channel sequencer automatically starts the air flow after the 5 minutes soak times, after the 6 minutes stops the air flow and sounds an alarm, and again sounds an alarm after the 10 minutes settling period other times are also available.
Model 28 is similar to Model 24 but upgraded for semi automated operation for increased precision and operator assistance. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Supplied with; Tubing Alternative diameter tube connectors Vacuum pump Solvent containers Mains lead Instruction manual.
Novel, sophisticated heating system and control allows the sample astmm reach test temperature in less than the 60 minutes specified by the method. Fan assembly for quicker cooling of Model baths. Automatic controller, d829 incl.
FOAMING CHARACTERISTICS OF LUBRICATING OILS ASTM D IP – NFT – ISO
Replaces silicones as heated bath medium. One channel totalizer installed in Model baths.
Inadequate lubrication, cavitation, and overflow loss of lubricant can lead to mechanical failure. This test method is used in the evaluation of oils for such operating conditions. Certified Mott metal cylindrical gas diffuser more uniform air bubbles and greater precision than Norton.
During cleaning an enclosed ashm is used to draw solvent and air through the diffuser in one direction which avoids particles or used solvent entering the diffuser and blocking the pores. A multi-pane insulated window allows full view of the test cylinder for observation of the foam. The Autowasdh is suitable for use with air inlet tubes of differing lengths and diameters.
For improved consistency of results, two digital indicating mass air flow controllers are used for precisely measuring and controlling the amount of air delivered to the air diffuser. An automated, two channel sequencer automatically starts the air flow after the 5 minutes soak time, after 5 minutes stops the air flow and sounds an alarm, and again sounds an alarm after the 10 minutes settling period other times are also available.
Recommended when using your own desiccant. Two channel digital flow control unit, upgrade from rotameter incl.
Also displayed is the time remaining to the next event requiring operator attention. Automatic-sequencing controller, automatically starts air flow after the 5 minute period of soaking the diffuser, sounds alarm and automatically stops air flow after 5 minutes blowing period, and sounds alarm after 10 minute settling period. Available as a stand alone model or incorporated into any of the foam testing baths. Foam Tester The foam tester allows the determination of the foaming characteristics of lubricating oils at specific temperatures by empirically rating the foaming tendency and the foam stability.
Historical Version s – view previous versions of standard. The foam tester allows the determination of the foaming characteristics of lubricating oils at specific temperatures by empirically rating the foaming tendency and the foam stability. Click for Software Screen. Silicone fluids are not recommended. ASTM D requires the recertification of the diffuser after 10 foam tests. The automatic wash programmes provides you with a consist clean that has significant benefits providing reliable and repeatable foam test results.
Novel, sophisticated heating system and control allows the sample to reach test temperature in less than the 60 minutes specified by the method. ASTM D recommends that the diffusers be tested when new and periodically thereafter, preferably after each use.
Two channel digital flow control unit, upgrade from rotameter incl. You can select a total of 10 programmes from the controller allowing you the choice of a single or two solvent wash with cycle times ranging from 3 to 19 minutes.

Caution should be taken when handling mercury and mercury containing products. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Both results are automatically displayed on the computer screen.
For specific warning statements, see Sections 78and 9. Recommended when using house air.
Sealing washer for between inlet tube and diffuser. The Lawler proprietary Windows software manages the testing operation and all the data.
Designed for pumping cold liquid to cool Model or H air foam bath. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: The chilled mixture is also helpful for rapid cool down of the air chamber for the next test.
It is equipped zstm a two channel automated sequencer, a two channel mass flow controller, and four temperature probes for the measurement of the sample temperatures.
Test assembly includes 1 of each: Air drying tower with Dririte desiccant and stand.
