It is used in the fields of electric power, coal, metallurgy, petrochemical, coalification, environmental protection, cement, papermaking, geological exploration, scientific research institutes and other industries to measure the carbon, hydrogen and nitrogen contents of coal, coke and petroleum.
1. The instrument uses infrared spectroscopy to measure carbon and hydrogen, and uses thermal conductivity to measure nitrogen.
2. The rest of the process is fully automated after stakeout, without manual intervention.
3. It has automatic detection of airway leakage.
4, there is a balance online function, automatic transmission of weighing results, can be networked.
5, can easily and quickly replace the furnace reagents and sputum.
