    Performance characteristics
    There are 39 one-time lofting turntables, and 78 one-time lofting turntables can be purchased. The weight of weighing sample can be automatically input by balance. The instrument can automatically send sample, drop sample and cycle test. There is no need for manual operation in the whole process after lofting, and samples can be increased, decreased and replaced at any time during the analysis process.
    The temperature control precision of the furnace can reach ± 1 ℃, and the temperature control precision of the constant temperature chamber and the gas storage tank can reach ± 0.1 ℃.
    The absolute pressure sensor is used to monitor the pressure of the whole gas path of the instrument, which can automatically detect the air tightness of the whole gas path, furnace, infrared cell, thermal conductivity cell and gas storage tank. The combustion process can be adjusted.
    The instrument uses infrared absorption method to measure carbon and hydrogen, and thermal conductivity method to measure nitrogen.
    5. The test speed is fast and the degree of automation is high. It only takes 5min / piece to test carbon and hydrogen separately, and 6min / piece to test carbon, hydrogen and nitrogen.
    When the experiment is finished, you can choose the option of "automatic cooling after the experiment". After the experiment is finished, the computer will automatically shut down and the instrument will automatically cool down. It can be unattended and does not need personnel to manually cool down and shut down after the test.
    7. The experimental report can be compiled according to the requirements of customers to reduce the workload of customers.

  • Chn-8000b full-automatic infrared hydrocarbon nitrogen analyzer is a precision analytical instrument built by Huanuo instrument with years of technical accumulation and according to the needs of users. It is characterized by excellent performance, complete functions, wide linear range, low detection limit, fast analysis speed, stable performance and simple operation. It can accurately determine the mass fraction of carbon, hydrogen and nitrogen in coal.
    Chn-8000b automatic infrared hydrocarbon nitrogen analyzer adopts desktop structure according to the existing laboratory conditions of customers. The lofting position of the instrument is only 52cm from the experimental table, which is convenient for customers to test.
    It is mainly used in power plant, coal mine, metallurgy, chemical industry, commodity inspection, scientific research, teaching and other departments to determine the content of carbon, hydrogen and nitrogen in coal.
