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 B 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.    Latest technology:adopt B method to instead of A method,There are no wood alloy in process of test to avoid
       environment pollution and personnel injure.
2.    Control method:adopting embedded operating system,high speed microprocessor control,work steadily and reliably. 
3.    Printing way:with USB printer port,RS232 port,realize the connection and communication between printers and
       computers.
4.    Touching:adopting LCD display,convenient operation by touch screen. 
5.    Safety:with the inner diagnostic program and many alarms,realize the smart management when instrument’s fault.
6.    Precision control:built-in high-capacity EPROM,real-time recording the value of temperature and pressure at each
       minutes.
