Liquid Petroleum Asphalt Flash Point Tester (Tag Open Cup Method)

Description

Summary
This instrument is designed and made as per T********3 Flash Point Determination for Liquid Asphalt by Tag Method in JTG E******1 Standard Test Methods for Bitumen
 and Bituminous Mixtures for Highway Engineering. It is used to test the liquid asphalt which flash point is lower than *3℃.
 
Main technical features
1.It adopts a special liquid heating system to heat the sample. It can ensure the safety of test. The heating power can be adjusted continuously.
2.Desktop structure. Stainless steel working bench and outer shell of heating furnace.
3.All parts are ready. User can do test as long as equipping civil gas and other natural gas.
