  • 产品名称 SDS820 Coulomb Sulfur Analyzer
  • description1 21 samples loaded once, high test efficiency.
  • description2 With digital flow meter, hygrometer, thermometer

Applications:
SDS820 can be used to determine the total sulfur content in combustibles such as coal, coke, petroleum and other solid biomass fuels in the field of power plant, coal mining, cement & steel factory etc.

Working principles:
A sample combusts and decomposes in air current with catalyst, the sulfur in coal produces sulfide in the reaction, and among the products, the sulfur dioxide absorbed by potassium iodide (KI) solution . Titrate the iodine produced by electrolyzing potassium iodide, and calculate the total sulfur content in coal according to quantity of electricity consumed when electrolyzing.
The total sulfur content, St, ad, of the sample, expressed as a percentage by mass, is given by the equation below:
St, ad=m1/m×100
Where
St, ad is total sulfur content in general analysis samples, expressed as a percentage by mass, %;
m1 is displayed in coulomb integrator, expressed in milligram, mg;
m is the mass of the sample, expressed in milligram, mg.
Highlights:
Accurate, precise and stable test result

①Optimized system design, complete sample combustion, full electrolysis of generated gases and thorough integration ensure accurate results.
②Electrolytic cell is fixed in the instrument. Electrolyte can be stirred uniformly, SO2 is electrolyzed thoroughly.
③Dilated and thickened platinum electrode plates, with bigger interface, make the integration more accurate and complete.
④The integrated systems are pre-configured with hardware which can avoid errors with software integration effectively. More accurate and reliable results are delivered.
Intelligent control
①Strong data processing capability by easy to use Windows-based software.Capable of connecting with network and balance by RS232 interface.
②With Ethernet communication technology, one PC controls several analyzers.
Humanization Design with stable performance
①With high quality furnace material, thermal insulation and life time is greatly improved.
②Unique drying tube design with high capacity efficiently reduces the desiccant replacement frequency.
③Reliable gas pump adopted, longer lifetime and lower maintenance frequency can be obtained.
④Gas leak check is convenient and fast.
High Automation
①Gas flow rate can be adjusted automatically without human attention.
②Chain type automatic sample sending device allows the adding and replacing of samples during test, 21 samples can be loaded once, then all samples’ introducing, testing and discarding are automatic and completed continuously.
