Product description


High Automation.

①Autoloader with 36 positions(72 optional),samples can be added or replaced in the process of testing.

②Automatic sample introduction and testing,realize to work unattended.


Short Thermostatic Time and High Test Efficiency.

①Independent and accurate thermostatic control for analyzer and sensor unit,thermostatic time only need 90 minutes.


High Precision.

①Sample introduction component adopted air curtain design,it can prevent the air into the furnace.and auxiliary by flow equalize unit,guarantee the sample combustion completed,avoid sample splashing when drop,ensure the test result is accurate.

②Adopted high-performance and precision IR sensor to testing the carbon and hydrogen element,and monitoring the combustion situation in real time,competently assess the combustion completion,shorten the test time and obtain a high precision test result.

③With high sensitivity and ultra low temperature drift diffusion type thermal conductivity cell,independent and accurate thermostatic control,ensure the thermal conductivity baseline stable.


Short and Reliable Gas Path.

①Adopted confluence board to integrated the gas path,low dead volume,short gas path and less water vapor residue,accurate and automatic flow control,gas path reliability improved.


Humanized Design, Easy to Operate.

①Easy and convenient to check the air tightness, operators only need to click on the software.

②Replace the crucible from the top of the analyzer,easy to change the furnace reagent and disassemble the furnace body.


Low Operation Cost.

①High stability IR sensor can get stability in short time,adopted throttling device,the helium consumption is only 0.7L/min during sample testing and 0.05L/min at other time.more efficiency than competitor and saving operation cost.
