Preferred Lianzhong instrumentation hydrogen tester performance requirements quickly and automatically hydrogen tester production base 

 Features: 1. 
 Mainly applicable to the determination of the content of the coal and other solid materials, organic and inorganic substances in hydrocarbon, coal, electric power, metallurgy and other sectors experiments essential equipment, a wide range of uses in the chemical industry, commodity inspection units. 2. 
 The entire testing process of the instrument using computer controlled by microcomputer variety of correction and processing of test data, the figures show that the number of milligrams of hydrogen-determination was, and replace the display determination of the final result - the unit weight of hydrogen burning kind of percentage content, and print out the total hydrogen values. Each sample measurement time about 10 ─ 15min, the accuracy and precision of the measurement results better than the national standard GB476-79. 3. Instrument compared with the three furnace combustion method determination quickly, accurate, simple operation, automation high touch keyboard input various data, printer played the final result, small size, light weight, laboratory than ideal hydrogen measurement instrument. 4. 
 The instrument can also be absorbed by weighing method to measure carbon, its accuracy and precision to meet the requirements of the national standard GB476-79. Technical indicators: 1, measuring range: hydrogen: 0 - 20%
