Lubricating Oil Evaporation Loss Tester (No Wood's metal method)    
ASTM D5800   DIN51581   CECL40A93    NFT6616
Model：JF0059

Product Introduction
When making this instrument, put the sample in the evaporation loss tester and heat it for 1 hour under certain conditions, and the evaporated oil will be carried out by the air correctly. Determine the evaporation loss of the sample based on the difference between the mass of the sample before and after heating. The instrument is suitable for lubricants and lubricant base oils.
