HTNJ-8A Automatic Bonding Index Tester

HTNJ-8A Automatic Bonding Index Tester is an instrument developed by our unit. This fully automatic bonding index tester integrates stirring, static pressure, and drum functions into a single unit. The experimental steps are fully automated, and users only need to press a button to initiate the test, making it the most advanced bonding testing instrument on the market. It is suitable for measuring the bonding capacity of coking coal—such as the Roga index and bonding index—in coal, metallurgy, coking, and laboratory research units. Complies with GB/T5447-2014 "Determination of Caking Index of Bituminous Coal."
