Introduction to Tangshan Jiaxiang Industrial Co., Ltd.: Production and sales of mining equipment; electricity supply; trading in mineral products (excluding precious metals), steel, construction materials (excluding timber, lime, and sand/gravel), refractory materials, metal products, iron ore, iron concentrate, machinery and equipment, electrical equipment, and automated control systems and their components; corporate management consulting services; general freight transportation; import and export of goods and technologies on a self‑operated and agency basis (for projects requiring approval under the law, business activities may be conducted only upon obtaining approval from the relevant authorities).

Tangshan Jiaxiang Industrial Co., Ltd. uses the following equipment manufactured by Changsha Youxin Instrument Manufacturing Co., Ltd.:

YX-DL8500 Automatic Sulfur Analyzer

Technical Features

◎ It adopts a horizontal integrated design, ingeniously integrating components such as the automatic sample‑feeding and injection mechanism, the high‑temperature pyrolysis furnace, the electrolytic cell, the stirrer, and the air‑purification system, thereby making the instrument more compact, more rational, and more stable.

◎ It employs a specially designed flat-bottomed corundum ceramic boat to minimize sample sticking. Program-controlled operation enables automatic heating, temperature regulation, sample introduction, and analysis; results are automatically saved and printed, and samples can be added mid‑run, significantly enhancing work efficiency and enabling truly unattended operation.

◎ The determination is performed using coulometric titration, with the analysis time automatically adjusted according to the sample type; this method offers superior speed compared to the Eschka gravimetric method and the high‑temperature combustion–neutralization method.

◎ Employs a linear electrolyte 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.

◎ A multi-point dynamic coefficient correction method is employed to ensure higher accuracy in test results for coals with high, medium, and low sulfur contents.

◎ Can be integrated with the laboratory management system to ensure that balance data is never stored locally and to enable backup and upload of test results.

◎It can be used to determine the total sulfur content in samples such as solid hazardous waste.

YX-WK7300A Rapid Muffle Furnace

Technical Features
