      High frequency inductive combustion furnace1. High frequency inductive
      combustion furnace output power:2200WFrequency20MHz.
      2. Auto-checking: Automatic overtime/over flow alarming system.
      3.The optional current/voltage/power regulator for furnace temperature
      control; it is applicable to samples of various materials.
      4. Gas paththe high precision flow controller ensures the stability of gas
      flow as well the gas intake system.
      Dust filter:0.4um submicron metal filter secures thorough separation of
      dust from gas.
      Furnace head heating Increase conversion rate of sulfur, to get a steady
      analysis result.
      De-dusting system:The combustion head self-cleaning devices effective for
      reducing the influence of dust for the result of analysis; ash removing
      system for the inlet.
      Detection system:1. Circuit design: the modularized design with double CPU
      for the whole frame is divided into the upper and lower levels, the lower
      one adopt Atmega162 to control the single machine, while the electronic
      circuits are highly integrated stably;
      2.SamplingAdopt high precision 24 leave ADS124 sampling CMOS chips,;
      3.Communicationthe upper and lower machine adopt USB terminal to increase
      the communicating speed;
      4.ConnectionInfrared detection parts and High frequency inductive
      combustion furnace connect with fiber, assorted with series shelter
      isolated circuit, avoid high frequency interfere;
      5. Light sourcethe tailor-made new model platinum infrared light source
      has lasting caloricity and efficient spectral property
      6.Analysis cell: the gilded carbon & sulfur analysis cell is fit with the
      high precision TSC infrared detector (1011);
      7. Motor: the special-purpose aviation modulation motor is applied with
      satisfactory thermal stability whose life expectancy exceeds 100000 hours.
      Instrument diameter and weight:Burning partsW70×H80×D55cm  Weight60kg
      Inspecting partsW55×H28×D45cm  Weight18kg
      Authorized standardISO9556ISO4935
      Operation system configuration Detailed information refers to the scope of
      supply.

2.2. Analyzing software
      Operating software:Adopt Deliph software,WINDOWS XP full Chinese operation
      interface.
      Analyzing route way:With channel management function, carbon and sulfur
      channel can increase, delete and edit separately without quantity limit.
      Preset low carbon and high sulfur interface.
      Analyzing function:Dynamic data accumulation when analyzing, 20times
      sampling per second, increasing the sensitivity and accuracy.
      With sample management function, can edit the name, mark of sample, also
      can do adding and deleting sample name.

      Display function:Separately curve frame for Carbon & Sulfur, dynamic show
      the data and Carbon & Sulfur release curve.
      Data processing function:Analysis results store by ACCESS data-base way,
      it can store data and curve every time; can search the results according
      to time, operator, sample name and mark any time; with curve/data storage,
      deduction of blankness, preset of parameters, channel selection, data
      statistic, result adjustment and curve preparing and other function. Can
      realize creating carbon and sulfur working curve and do the curve fitting
      in the software.
      Printing function:Printing mode diversification: Laboratory and inspection
      station printing mode and can self-design proper mode.
      Self-diagnose function:System self-diagnose function,can realize checking
      furnace head and sealing performance of the gas chamber by the soft ware.
