determine mercaptan sulfur in gasolines,kerosines,aviation turbine fuels anddistillate fuels containing from 0.0003~0.01% (m/m) 

Purpose:

FDQ-1201  Thiol Mercaptan Sulfur Analyzer is designed and made as per the National Standard GB/T1792 “Test Methods for Mercaptan Sulfur in Distillate Fuels (Potentiometric Titration Methods)”. It is suitable to determine mercaptan sulfur, which is in the range of 0.0003~0.01% (m/m), in the jet fuels, gasoline, kerosene, andlight diesel, which do not contain hydrogen sulfide.

FDQ-1271  Thiol Mercaptan Sulfur Analyzer is composed of FDQ-1201  PHS-3B pH meter, FDQ-1201  Magnetic Stirrer andother accessories. It is a standard instrument used for determining mercaptan sulfur in distillate fuels.
