Fluorite Sulfur Content Tester
0.001-100% 0.005% (Working Principle
The test sample is burned under high-temperature conditions in a purified air stream, where all forms of sulfur in the sample are decomposed by combustion. The sulfur is carried by the air stream into the electrolytic cell, where it combines with water to form H?SO?. This disrupts the dynamic equilibrium of the original iodine-iodide pair in the electrolytic cell, prompting the instrument to immediately output current to electrolyze potassium iodide solution, generating iodine to restore the original dynamic equilibrium. The amount of current consumed to restore this equilibrium correlates with the sulfur decomposed from the test sample, which is measured and calculated by the microprocessor.
