Features:

● Computer-controlled temperature regulation and volume curve plotting according to the national standard GB/T479-2016 "Determination of Caking Index of Bituminous Coal". Uses Mitsubishi PLC to control an intelligent robotic arm for automatic measurement of the upper and lower layer thicknesses of the plastic layer, automatically plots the upper and lower layer curves, and calculates results, significantly reducing labor intensity and human factors.

●Equipped with a built-in ventilation and smoke exhaust system, eliminating the need for a fume hood during testing. Utilizes well-known brand exhaust fans for effective automatic smoke extraction, reducing laboratory configuration requirements and saving costs.

●Automatic weight loading technology eliminates manual weight handling. Lever-free design enables automatic control of weight attachment and removal.

●Automatic probe alignment design adjusts the parallel angle between the probe and paper tube to ensure precise alignment, improving test reliability and stability while enhancing usability.

●No need to attach or detach the volume sensor manually, preventing test failures due to human oversight and improving testing stability.

●Rapid furnace brick replacement. After testing, an electric drive mechanism quickly replaces the furnace brick for the next experiment without waiting for cooling, improving experimental efficiency.

●Dynamic display of temperature curves, volume curves, and system operational status. The measurement process requires no manual intervention, strictly adhering to national standard methods.

● Temperature control, X-value, and Y-value measurements are independently performed by the computer with real-time data saving. Allows querying of real-time and historical data (including temperature and volume curves).

● Features power-off protection, automatic peak and trough recognition, and measurement to ensure scientific and accurate data collection.

● Capable of resuming pre-power-off operation after power restoration and continuing until the experiment concludes.

● Stable and reliable PLC control system with automatic fault detection (measurement, heating, temperature control), alarm alerts, and power cutoff for safety protection.

● Option to conduct single or dual furnace tests; exposed electrical parts such as silicon carbide rods and clamps are isolated for protection.
