KZCH-6A Microcomputer Automatic Hydrogen Analyzer

Operational principle:

The principle of hydrogen determination: a certain amount of coal sample is burned in the oxygen flow, the water generated reacts with phosphorus pentoxide to form metaphosphate, electrolysis of metaphosphate, according to the consumption of electricity, calculate the hydrogen content in coal;

The principle of carbon measurement: A certain amount of coal sample is burned in the oxygen flow, the carbon dioxide generated is absorbed by the carbon dioxide absorbent, the carbon content in the coal is automatically calculated by the increment of the absorbent.

Performance features:

It is suitable for the determination of the content of organic and inorganic hydrocarbon in coal and other solid materials. It is an experimental instrument in the fields of coal, electric power, metallurgy, etc.

The rapid automatic hydrogen analyzer features a fully computer-controlled testing process, with the microcomputer performing multiple corrections and data processing. It displays the hydrogen content in milligrams per unit weight of the sample and can switch to showing the percentage of hydrogen burned per unit weight, while also printing the total hydrogen value. Each sample analysis takes approximately 10-13 minutes, with results demonstrating accuracy surpassing GB476-91 standards.

The combustion furnace is made of quartz and fully sealed, with a length of 90cm. The sample feeding mechanism is operated inside the combustion furnace, and the sealing is good.

The instrument is designed as an integrated system with a novel and elegant appearance. The carbon measurement device and the instrument are combined into one, making the carbon measurement process more convenient and straightforward.

The reasonable design of airway can avoid the leakage and blockage of airway.

Automatic data processing; automatic printing of results (optional touch screen analyzer);

Automatic temperature control, timing, simple operation.
