Fison Elemental (CHN) Analyzer performs rapid carbon, hydrogen, and nitrogen determination in 300 seconds per sample across environmental, petroleum, coal, chemical, pharmaceutical, agricultural, and food-testing applications. Its layered auto-feeder accommodating up to 140 units across four levels, resistance furnace heating to 1050°C, and infrared/thermal-conductivity detection module maintain measurement stability and consistent throughput. Fixed combustion adjustments and remote monitoring capability minimize manual intervention and calibration drift across high-volume batch runs. Manufactured for industrial and research laboratories with frequent workloads, the CHN instrument complies with ASTM D5373-2014 methodology, featuring a compact footprint and low-maintenance design that support continuous quality-control operations.
