Gd-387 Dark Oil and Diesel Sulfur Analyzer

I---Brief Introdcution:
The instrument is designed and made as per the national standard of People's Republic of China GB/T387 Test Method for Sulfur Content of Dark Petroleum Products (Tubular Oven Methods).
It is used to determine the sulfur content in dark petroleum products, the sulfur content of which is more than 0.1% (m/m), as per GB/T387.
Completely burn the quartz boat containing sample in the purified high temperature air at a certain flow rate and absorb sulfurous acid anhydride and sulfuric acid anhydride created during this procedure using oxidized hydrogen and sulfuric acid. Then titrate sulfuric acid using standard sodium hydroxide solution.
