HT-TGA8200 Thermogravimetric Analyzer/Proximate Analyzer

Capabilities: Complete moisture, ash, and volatile matter tests for 20 samples within 90 minutes.

Application Scope:

Determination of moisture, ash, volatile matter, and calculation of fixed carbon, hydrogen content, and calorific value in coal, coke, ores, carbon black, asphalt, and solid biomass fuels.

Analysis of combustible content in fly ash and slag.

Analysis of moisture, ash, and volatile matter in calcined petroleum coke.

Analysis of loss on ignition in cement.

Technical Features:

1. Standardized Process, Accurate Results: The testing process, conditions, and results for moisture, ash, and volatile matter meet national standards, requiring no correction, and can be used for arbitration analysis.
2. Extremely Fast Testing Speed: Experiments can be conducted immediately after startup. The multi-furnace, dual-balance structure with a constant-temperature drying device allows for the combination or separate measurement of moisture, ash, and volatile matter. Three indicators for 20 samples can be tested simultaneously within 90 minutes (fast method).
3. High Automation: Utilizes advanced computer real-time communication technology and adaptive control technology. High-precision imported electronic balances are integrated into the instrument, combined with automatic weighing mechanisms, and thermogravimetric analysis. Automatic sampling, data processing, result calculation, report printing, and storage enable unattended operation.
4. Simple and Safe Operation: No need to handle crucible lids, feed, or retrieve samples during the experiment. Imported cylinders automatically control the opening and closing of the water and ash covers, avoiding high-temperature radiation and burn risks.
5. Accurate Temperature Control: The cylindrical high-temperature furnace ensures uniform temperature distribution. The optimized process avoids temperature field disturbances caused by frequent opening of the furnace door in assembly line operations. Advanced PID temperature control algorithms ensure a control accuracy of 1℃.
6. Patented Insulation Mechanism: Ensures a stable and interference-free working environment for the built-in balance.
7. Classic Structural Design: Patented weighing and feeding mechanisms improve weighing and feeding speed, reducing testing time. The absence of “mechanical arms” or sliding rail translation devices prevents accidents such as crucible dropping, misalignment, or breakage during transfer.
8. Thermal Balance Weighing Technology: A single sample tray eliminates the need for frequent sample movement between combustion and weighing trays. Calibration is performed in the same atmosphere using a blank crucible, avoiding weighing errors caused by inconsistent crucible temperatures in assembly line operations. Multiple weighing methods are available.
9. Strong Adaptability: A silent air compressor can be used to provide compressed air for driving pneumatic devices and combustion, eliminating the need for any bottled gas.
