Introduction: This instrument is designed and manufactured in accordance with the requirements of the People's Republic of China GB / T 387 "Determination of sulfur content of dark petroleum products (pipe furnace method)" and is applicable to the determination of sulfur content according to the method specified in GB / T 387 Greater than 0.1% (m / m) of sulfur content in dark petroleum products. The instrument through the sample with the quartz boat, in the fixed flow of purified high temperature hot air flow in the complete combustion, with hydrogen peroxide and sulfuric acid solution, the resulting sulfurous acid anhydride and sulfuric acid fully absorbed, the resulting sulfuric acid Titration with sodium hydroxide standard solution. Features: 1. The instrument is mainly composed of tube furnace, furnace temperature control device, air flow indicator device, display device and other components. 2. The use of single-chip intelligent control system, detection time, furnace movement, when the alarm and other functions to achieve automatic control. 3. According to the requirements of the furnace body to move the way, the instrument in accordance with the requirements of the test procedure, the furnace will automatically move, automatically stop and automatically return to the initial working state. 4. The instrument is designed with horizontal parallel double-tube resistance furnace, which can test two samples at the same time, the test efficiency is high, the test results are accurate and reliable. 5. With built-in gas supply and external air supply interface, you can use the internal air supply, you can also use external air supply.
