Flat bottomed glass mL graduated test cylinder starting at 10mL and continuing at 10mL increments. PC controlled apparatus visual first bubble detection.
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.
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability d829 regulatory limitations prior to use. Also displayed is the time remaining to the next test event requiring operator attention. Even low levels 1 ppm and above of silicone contamination interfere with test results.
Foaming Characteristics: Foam Tester ::
Get in touch Document Finder. 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. Model 24 dual foam test bath is the traditional arrangement with two glass jars mounted on a supporting base. However, the manometer is replaced by a high precision digital pressure controller.
Supplied with; Tubing Alternative diameter tube connectors Vacuum pump Solvent containers Mains lead Instruction manual. Model uses a digital indicating 0. The Lawler proprietary Windows software manages the testing operation and all the data.
Four position sample storage rack cylinders not included.
Certified Mott metal cylindrical gas diffuser more uniform air bubbles and greater precision than Norton. Two channel totalizer installed in Model baths. Designed for pumping cold liquid to cool Model or H air foam bath. PAO fluid has longer life at higher temperatures then conventional bath medium oils.
A touch screen allows the operator selection and full adjustment of all test parameters. 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.
PAO fluid has longer life at higher temperatures then conventional bath medium oils. One channel totalizer installed in Model baths.
Both results are automatically displayed on the computer screen. The chilled mixture is also helpful for rapid cool down of the air chamber for the next test. Fan assembly for quicker cooling of Model baths. For specific warning statements, see Sections 78and aastm.
Foaming Characteristics: Foam Tester
For improved consistency of results, two digital indicating mass flow controllers are used for precisely measuring and controlling the amount of air delivered to the air diffuser. This is calculated by the software program. The use of heated air to heat the test samples improves the overall safety by eliminating the use of the potentially unsafe, smoking, dripping of, flammable, hot liquid bath medium.
All key parameters are displayed during the test. The values given in parentheses after SI units are provided for asmt only and are not considered standard. Two channel digital flow control unit, upgrade from rotameter incl. Recommended when using your own desiccant. Once you start a programme you can leave the Autowash unattended and the instrument sounds an audible warning when the cycle has finished.
