  • 产品名称 SDCHN435 Carbon Hydrogen & Nitrogen Analyzer
  • description1 10 Patents. 7 Invention patents included.
  • description2 The only type of elemental analyzers with auto combustion crucible replacing device.

Application:
SDCHN 435 can be used to determine the carbon, hydrogen and nitrogen content in coal, coke, food, soil, fertilizer etc in the fields of power plant, coal mine, metallurgy industry and so on.

Highlights:
High Precision.

①With high-performance infrared light supply, superior optical glass as well as pure gold infrared path and precise thermostatic control, the drift of the infrared cell and TCD is greatly optimized.
澳门新葡京网址大全
①Easy and convenient for gas leakage check, operators only need to click on the software.
②Enlarged combustion crucible can greatly reduce the frequency of crucible changing (Approximate every 350 tests).
澳门新葡京网址大全

①Strong data processing capability by easy to use Windows-based software.
②Capable of connecting with network and balance by RS232 interface.
③With CAN bus communication technology, one PC controls several analyzers.
④Separate reagent tube design,reagent can be replaced conveniently and safely.
Patent No.: ZL200710303472.4

High automation and test efficiency.
①Autoloader with 34 position, automatic sample introduction and test.
②Combustion crucible can be replaced automatically,without disassembly or cooling.
③Analysis time/sample≤5 minutes, new samples can be added or replaced during the analysis process.
④Calibration every 3 hours or lower frequency by self developed ultra-low drift infrared cell.
Low operation cost.
①Helium consumption is only 0.7L/min for each test. Nitrogen analysis part can be stopped optionally.
(SDCHN435 only)
②Oxygen with purity of 99.5% can meet the test requirement.
