Description
Purpose:
GD****2 Fuels Mercaptan Sulfur Tester is designed and made as
per the National Standard GB/T***2 “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.***3~0.*1% (m/m), in the jet fuels, gasoline,
kerosene, and light diesel, which do not contain hydrogen
sulfide.
GD****2 Fuels Mercaptan Sulfur Testeris composed of GD******1
PHS*3B pH meter, GD******2 ***1 Magnetic Stirrer and other
accessories. It is a standard instrument used for determining mercaptan sulfur in distillate
fuels.
