ASTM D4929 Microcoulomb Sulfur and Chlorine Analyzer

Microcoulomb Sulfur and Chlorine Analyzer

Product model: JF3246

Product Introduction

Microcoulomb sulfur chloride analyzer is based on national standards GB/T11061-1997, GB/T18612-2011 and industry standards SY/T7508-1997, ASTM D3120, ASTM D4929-2017, SH/T0253-1992, SH/T0222-1992, According to the microcoulomb principle, sulfur (chlorine) of various forms in the sample is changed into sulfur dioxide (all become HCl) in nitrogen and oxygen at high temperature, and enters the titration tank, where iodine reacts with sulfur dioxide through electrolysis (silver ion reacts with chloride ion through electrolysis in the tank). The computer automatically calculates the total sulfur content (total chlorine content) of the sample according to the electricity consumed by the iodine produced (the computer according to the electricity consumed by the silver ions produced) and according to Faraday's law. The whole analysis process is controlled by computer, the sample is loaded by automatic sampler, the instrument has a high degree of automation. Can be used for the analysis of trace sulfur or chlorine in petrochemical products, widely used in petroleum, chemical, scientific research, teaching, environmental protection, quality inspection, commodity inspection and other industries.

Performance characteristics

1. The most complete configuration, the widest range of use, according to the form, density automatically converted into the corresponding parameters, good performance, high degree of automation.

2. Computer control, display the whole process state, figure the whole titration process parameters, then save the data, so as to facilitate the query, print various results.

3. The furnace body and the main engine adopt the shielding device, completely eliminate the risk of furnace temperature runaway, but also completely solve the interference to the baseline of titration tank in the heating process.

4. Simple operation, reliable performance, good stability, easy installation, cracking system for air cooling, fan automatic start and stop.
