Application:
SDIS450 can be used to determine the sulfur content in coal, coke, ash, biomass fuels and other combustibles in the fields of power plants, coal mines, petrochemical, paper & steel factory etc.
Highlights：
High Automation, high test efficiency.
①Analysis time / sample is＜2 minutes. Samples can be placed in process of test.
②50 autoloader design, high automation, no need attendance in the whole process. Manual sample introduction is also available.
③Patented technology of combustion gas curtain effectively ensures thorough combustion of sample and no emission of gas. Safe and environmental friendly.
④Filter wool can be replaced automatically, no damage to combustion tube and furnace.
⑤Easy and convenient for gas leakage check, operators only need to click on the software.
Humanization Design with stable performance.
①Tailored boat shaped crucible can be placed at random.
②Automatic identification of crucibles by locator card, no need coding in advance.
High Precision.
①Specially designed high temperature combustion tube with secondary combustion function, makes sure the samples combust thoroughly.
②Self-developed ultra low drift infrared cell guarantees that only one drift in a working day is enough for accurate test.
Intelligent control.
①Easy to use Windows-based software: It only needs to click the mouse after weighing and placing the samples.
②Easy data handling, real time data can be transmitted by internal network.
③With Ethernet bus communication technology, one PC controls several analyzers.
④Capable of connecting with network and balance by RS232 interface.
