Product Introduction

Used in industries such as power, coal, metallurgy, petrochemicals, coal chemicals, environmental protection, cement, papermaking, geological exploration, and scientific research institutions to measure the carbon, hydrogen, and nitrogen content in materials like coal, coke, and petroleum.

Performance Features:

■ High efficiency: Pneumatic sample tray with continuous feeding, capable of loading 36 samples at once.

■ Fast testing process: Allows cyclic sample addition and insertion of new samples at any position, enabling immediate testing upon sample arrival.

■ Compact and elegant: The smallest and lightest elemental analyzer on the market.

■ High automation: Automatic sample dropping, experimental process control, data processing, result calculation, and report printing, with features like automatic cooling, gas saving, and software/computer shutdown, enabling unattended operation.

■ Externally mounted furnace with a compact integrated structure; combined carbon, hydrogen, and nitrogen testing furnace avoids damage to critical constant-temperature internal components from slow heat dissipation and ensures data stability.

■ All test samples must be calibrated using a first-order curve; second or third-order curves are not applicable.

■ Easy maintenance: Automatic gas path fault diagnosis and leak detection, reducing instrument maintenance difficulty.

■ Intelligent energy-saving control: Automatically cools down after testing or prolonged standby, maintaining a low target temperature to save energy and extend the lifespan of high-temperature components.

■ Convenient testing: Combines fixed combustion processes with automatic adjustments to minimize user testing costs while ensuring accurate results.

■ Long service life: High-stability infrared cell with fully independent intellectual property rights, low drift, high efficiency, and durability.

■ Remote monitoring: The instrument can be connected to laboratory management systems via network interfaces for automatic data upload and full-process supervision of testing.

■ Equipped with pressure sensors and software for gas path diagnosis and calibration.

■ Configurable with automatic sample packaging devices and compatible with unmanned testing systems.

■ Built-in filtration reaction chamber allows direct testing of samples without blank samples.
