This instrument is suitable to determine closed cup flash point of petroleum products.
The test method is:continuously stir and heat the sample with slow constant speed.Under specified temperature interval,stop the stirring,and put small flame into test cup.Then the lowest temperature of vapour flash caused by the flame is the flash point.
