Brief introduction:
SH709 automatic thiol sulfur tester adopts the principle of potentiometric titration. The sample without hydrogen sulfide was dissolved in isopropanol solution of sodium acetate, potentiometric titration was carried out with silver alcohol standard solution, pH glass electrode was used as reference electrode, thiol-sulfur electrode was used as indicator electrode, and the potential jump between the two electrodes indicated the titration endpoint. In the titration process, thiol sulfur precipitates to silver thiol. The SH709 thiol sulfur meter conforms to GB/T 1792, ASTM D3227 and other standards. It is suitable for the determination of thiol-sulfur in non-hydrogen sulfide jet fuel, gasoline, kerosene and light diesel fuel.
