Product Description
Technical Features
Technical Specifications

- Commodity name: YX-DL8501 Automatic Sulfur Analyzer
- 仪器标准配置: 1 computer + 1 printer + 1 set of YX-DL8501 host unit
- 技术特点: By employing an MCPC control module and a touchscreen, the instrument’s status is monitored in real time, its parameters are saved, and the entire testing process is executed autonomously without requiring host‑computer intervention, enabling standalone operation and self‑diagnostic alerts, thereby significantly enhancing the instrument’s reliability.
Based on the principle of coulometric titration, this method is suitable for determining the total sulfur content in combustible materials such as coal, coke, petroleum, and solid biomass fuels, as well as the sulfur content in cement.

Scope of Application

Based on the principle of coulometric titration, this method is suitable for determining the total sulfur content in combustible materials such as coal, coke, petroleum, and solid biomass fuels, as well as the sulfur content in cement.

Conform to the standards

GB/T 214 “Method for Determination of Total Sulfur in Coal”

GB/T 43218 “Guidelines for Performance Acceptance of Coal Sulfur Analyzers”

JJG 1006 “Verification Procedure for Instruments for Determining Total Sulfur in Coal”

GB/T 483 “General Provisions for Coal Analysis Test Methods”

GB/T 387 “Method for Determination of Sulfur Content in Dark Petroleum Products”
Key words:
◎ Determination is performed using coulometric titration, with the measurement time automatically adjusted according to the sample type; this method offers faster analysis than both the Eschka gravimetric method and the high‑temperature combustion–neutralization method.

◎ Equipped with an MCPC control module, the instrument provides real-time status monitoring, saves instrument parameters, and completes test procedures independently without requiring host‑computer intervention, enabling standalone operation and self‑diagnostic alerts, thereby significantly enhancing instrument reliability.

◎ Equipped with a high-precision angular encoder control system, it can load 41 samples at once, ensuring precise positioning and preventing sample jams.

◎ The horizontal integrated design ingeniously combines components such as the automatic sample‑feeding mechanism, high‑temperature pyrolysis furnace, electrolytic cell, stirrer, and air‑purification system, resulting in a more compact, rational, and stable instrument configuration.

◎ Equipped with a high-precision electronic flow meter, it can directly display the gas flow rate and automatically trigger an alarm when the flow deviates from the set range.

◎ Equipped with power‑off memory, the system retains test data even if the test is interrupted unexpectedly; upon power restoration, it automatically resumes the test.

◎ The entire testing process is fully automated, with results automatically saved and printed, and samples can be added mid‑test, significantly boosting efficiency and enabling unattended operation.

◎ Employs a linear electrolyte‑molecule concentration acquisition circuit, effectively addressing the issue of electrolyte over‑consumption.

◎ Employs a contactless switch, featuring open-circuit protection, hardware over-temperature protection, and measures to prevent electrolyte backflow.

◎ The instrument features automatic delayed shutdown and automatic computer shutdown upon completion of testing.

◎ Can be integrated with the laboratory management system to ensure that balance data is never stored locally and that test results are backed up and uploaded.

◎ Suitable for determining the total sulfur content in samples such as solid hazardous waste.
