Description
ONH-330 oxygen nitrogen hydrogen analyzer
Product Profile:The oxygen, nitrogen and hydrogen analyzer melts the sample at high temperature under the protection of inert gas through a pulse electrode furnace. The oxygen in the sample reacts with the carbon in the graphite crucpot to form carbon monoxide (CO). Nitrogen and hydrogen escape in the form of nitrogen (N2) and hydrogen (H2) respectively. After passing through the converter, the gas mixture is sent to the infrared detection system for detection, and then the gas mixture containing nitrogen (N2) and hydrogen (H2) after removing carbon dioxide (CO2) is sent to the thermal conductivity detector for detection. Infrared detection system and thermal conductivity detection system will measure the signal after amplification, A/D conversion processing, through the computer data processing, so as to calculate the content of oxygen, nitrogen, hydrogen in the sample.Decide to lead is technology, but also stable and reliable quality. The new generation of oxygen, nitrogen and hydrogen analyzer breaks through the past with a new attitude. It not only has the advanced design of the whole machine integration and modularization, but also has high-precision and high-reliability parts, as well as reliable pulse electrode furnace, reliable and durable power supply, advanced and stable circuit system, reasonable layout and good air tightness gas circuit system, and highly sensitive and high-precision detection system. More based on Windows10 operating system powerful, simple, practical analysis software, so as to bring you more cost-effective products. For more details, please contact us.
