Selected automatically hydrogen tester Come the Hebi OurGame measuring range | temperature control | equipment size 

 Can be characterized by: 
 A. 
 Mainly applied to the determination of the content of hydrocarbon in the organic and inorganic matter in coal and other solid materials, coal, electricity, metallurgy and other sectors of the necessary experimental apparatus, while in the chemical industry, commodity inspection, and other units also have a wide range of uses. 
 Two. 
 The instrument testing process using computer control, a variety of calibration and processing by the microcomputer of the test data, and figures show the number of milligrams of hydrogen in the determination of material replacement, and can display the final results of the determination-unit weight, burn-like hydrogen percentage content, and print out the value of the total hydrogen. Each sample measurement time is about 10 ─ 15min, accuracy and precision of measurement results is better than GB GB476-79. 
 (3) of the instrument compared with currently used by three furnace combustion method with determination of rapid, accurate, simple to operate, high degree of automation, touch keyboard to input various data, printers, play the final result, small size, light weight and other characteristics, is the current experiments Room ideal for hydrogen measurement instrument. 
 (4) The instrument can also weighing absorption method to measure the carbon, its accuracy and precision to meet the requirements of national standard GB476-79.
