K44000 Noack Evaporation Loss Apparatus & Data Acquisition Software

K44001 Noack Evaporation Loss Analyzer and Accessories

Test Method
A quantity of 65g of a lubricant is placed in an evaporative crucible and heated to 250°C for 60 minutes. The evaporation loss tendencies of the lubricant are determined by passing a constant air stream over the heated sample by means of a vacuum pump.

Features and Benefits

• Conforms to ASTM D5800, DIN 51581 specifications

• Non-woods Metal or Woods Metal heating bath

K44000 Noack Evaporation Loss Apparatus
K44000 Noack Evaporation Loss Apparatus
The Koehler Noack Evaporation Loss Analyzer tests the evaporation loss tendencies of lubricating oils at temperatures of up to 350°C, available with either a Non-Woods Metal or a Woods Metal heating bath.

Non-Woods Metal Option
Fully insulated aluminum block heating unit has a microprocessor-based digital temperature and pressure controller. A digital stopwatch is also included for recording test and cooling times. The test is started automatically after insertion of the crucible and displays both temperature and pressure curves in real-time throughout the test. The stainless steel evaporation crucible inserts into the aluminum block oven and includes a plated brass lid assembly with threaded support ring, hardened steel air nozzles, and extraction tube with threaded and sealed connection. Order required accessories separately.

Woods Metal Option
Fully insulated aluminum block heating unit has a microprocessor-based digital temperature controller and stopwatch for recording test and cooling times. The evaporation crucible is identical as listed above. Aluminum block accepts certified thermometers for temperature monitoring. Order required accessories, vacuum pump, and automated pressure control unit separately.

K44000-SFW Noack Software
Noack Software automatically retrieves in real-time complete test parameters including temperature, pressure, and elapsed test time, providing hands-free data acquisition. The software defaults to monitor temperature at 250 ± 0.5°C and pressure at 20±0.2mm H2O; however, these parameters are easily changed for other user specifications. The software will indicate whether the temperature or pressure values exceed the user-defined limits during the test. 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. Direct communication with the Koehler analytical balance eliminates weighing errors by recording values directly from the balance with a simple click of the mouse. The "test intelligent" software simplifies the testing process by providing sequential test prompts for assisting the operator with each step of the test procedure. The active zoom, pan, and trace feature allows the ability to change axes and the magnification of any sector of the pressure or temperature graphs to view data in greater detail. The final test data is exported with graphs and test parameters 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.
