SUNDY SDS516 Kükürt Analiz Cihazı

SDS516 Kükürt Analiz Cihazı



Coulomb Sulfur Analyzer 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
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;
m2 is the mass of the sample, expressed in milligram, mg.

  • With chain type automatic sample sending device which allows adding and replacing samples during tests, the instrument could accept 17 samples at once. All samples’ introducing, testing and discarding are automatic and completed continuously.
  • Horizontal furnace with a super wide uniform temperature zone(≥90mm) ensures complete combustion of coal samples.
  • Equipped with dilated and thickened electrolysis electrodes and a unique positioning slot which ensures that the electrolytic cell is fixed at the same position every time, the SDS616 can stir the electrolyte more evenly and then electrolyze the gases more completely.
  • Gas leak check is convenient and easy.
  • With CAN bus, several calorimeters can be controlled by a single PC without mutual influence.
  • Balance could be connected and data could be transmitted by real-time network transmission.
