The HT-2000 Coking coal Reactivity and Post-Reaction Strength Tester is an instrument used to measure the reactivity index of coke. This equipment employs PLC control and an industrial touchscreen for display. The high-temperature furnace’s temperature is regulated using closed-loop fuzzy logic PID control, while the PLC system comprehensively monitors and processes the central temperature of the furnace chamber. The touchscreen allows for operation and modification of PLC parameters, with dynamic display of variable curves.
