Summary
  The Instrument is designed and manufactured according to Industry standard NB/SH/T 0059-2010 and ASTM D5800 Standard test method for evaporation loss of lubricating oils by the Noack A method.It’s suitable to determine lubricating oil(especially internal combustion engine oil) and the evaporation loss of lubricating base oil at 250℃.

I.Main technical features
1. With the color touch screen,all data real-time display,parameters input and adjustment,test results etc are all operated and checked on touch screen,with the advance technology and convenient operation.
2. Adopting the heating device of metal bath,safety and environmental protection.
3. With the imported precision differential pressure gauge and precision needle valve pressure regulating system,ensure the accuracy of test pressure.
4. The bath with wood alloy has the excellent property of heat conduction.
5. Evaporation crucible fit the ASTM and NB/SH/T 0059 standard.
6. Equipped with the professional vacuum draw system and buffer device,ensure the stability and reliability in the process of suction.
7. With the singlechip and high precision temperature sensor,temperature control is accuracy and high precision.
