GD-1792 Distillate Fuels Mercaptan Sulfur Tester
產品型號:GD-1792
產品分類:自動化設備/產業機械 / 檢測設備 / 檢測、量測設備及其另件
產品特色
Purpose:
The instrument 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, and light diesel, which do not contain hydrogen sulfide.
The instrument is composed of GD-1792-1 PHS-3B pH meter, GD-1792-2 95-1 Magnetic Stirrer and other accessories. It is a standard instrument used for determining mercaptan sulfur in distillate fuels.
