| KOEHLER K441X0 Evaporation Loss of Lubricating Oils by the Noack Method |
| Test Method For determining the evaporation loss of lubricating oils, particularly engine oils. High temperatures can evaporate oil which may contribute to oil consumption in an engine and can lead to a change in the properties of an oil. A measured quantity of sample is placed in an evaporation crucible that is then heated to 245.2°C with a constant flow of air drawn through it for 60 minutes. The loss in mass of the oil is determined. |
| Automatic Non-Woods Metal Noack Evaporative Apparatus • Conforms to ASTM D5800, Procedure B • 6.5” Integrated Touch Screen Panel PC • Integrated Vacuum Pump with automatic electronic control system • Direct sample temperature measurement via PT100 probe • Equipped with high resistant Kalrez valve, inlet filter to remove product residuals • USB port for connection to an external printer and/or external PC • Storage capacity for more then 60,000 analysis • CE Marked The Automatic Non-Woods Metal Noack Evaporative Apparatus tests for the evaporation loss tendencies of lubricating oils at temperatures of up to 275°C. The newly designed electrically heated aluminum block allows for testing without the use of hazardous Woods Metal. The Noack tester is equipped with an Electronic regulator allowing for automatic control of temperature and differential pressure. The system is managed by an integrated 6.5” Touch Screen Panel PC by means of the Noack Evaluation Software run by a Windows® based operating system. The Evaluation Software is capable of recording all analytical parameters, allowing for user customizable parameters, methods and result reports as well as printing graphs and test results.
