HT-DL910 Fully Automatic Sulfur Analyzer is used in industries such as power, coal, metallurgy, petrochemicals, environmental protection, cement, papermaking, geological exploration, and scientific research institutions for the determination of total sulfur content in coal, coke, and petroleum. Its main feature is that after manual weighing and sample placement, the instrument can automatically and continuously perform batch operations, and samples can be dynamically added at any time, greatly improving testing efficiency.

It adopts a horizontal furnace structure and corundum boats for coal sample placement.

Instrument Overview:

1. Accurate, Precise, and Stable Test Results:
   1. Optimized system design ensures complete sample combustion, SO2 electrolysis, and current (charge) integration.
   1. High-precision, low-drift hardware integration signal circuit design. A separate microcontroller performs hardware integration during electrolysis, completely overcoming the issue of data omission in software integration, ensuring complete integration and accurate measurements.
   1. Dual-rod sample feeding mechanism significantly improves feeding stability. Unique chain anti-scratch design effectively avoids sample flipping and jamming.
   1. Wider and thicker platinum electrolysis electrode (195mm²) and indicator electrode (77mm²), with areas increased by 30% and 4 times respectively compared to ordinary instruments, ensuring larger contact area and more precise and complete integration.
2. High Automation:
   1. After placing 21 samples at once, the instrument automatically feeds, tests, ejects, and discards samples, enabling unattended operation. Samples can be added or replaced during the experiment.
   1. Uses a digital flow meter for real-time gas flow display.
3. Stable Operation and User-Friendly Design:
   1. The system design fully considers the anti-fatigue performance of the instrument (especially components under high-temperature conditions). The high-temperature furnace uses imported new materials with excellent insulation and long service life.
   1. Unique working model and device design minimize water vapor entering the drying tube. Combined with a large-capacity drying tube, it effectively reduces the frequency of desiccant replacement, operator workload, and operating costs.
   1. Uses a stable, maintenance-free air pump with no need to replace rubber cups, ensuring long service life.
   1. Convenient air-tightness check: Operators can complete it with a simple finger swipe.
   1. New electrolytic cell leakage corrosion protection design prevents corrosion caused by abnormal leakage.
