Detailed Description

A:Brief description: DSHD-1792 Mercaptan Sulfur Tester is made according the national standard GB/T1792-88 Distillate fuels－Determination of mercaptan sulfur－Potentiometric titration method. 　　　DSHD-1792 Mercaptan Sulfur Tester is composed of PHS-3C PH meter, 95-1 magnetic stirrer and support device. 　　　Its function is to determine the mercaptan sulfur in jet fuel, gasoline, kerosene and light diesel without hydrothion, and the content is within the range of 0.0003～0.01%(m/m). Interferences will appear when elemental sulfur is over 0.0005%（m/m） B:Technical parameters DSHS-3C PH meter1. Grade of instrument: 0.012.
