Product Introduction:

The natural gas analyzer GC-7900R is suitable forThe component content analysis and detection of pipeline gases such as natural gas, liquefied gas, liquefied mixed air, and gas distribution. The instrument's built-in analysis software system can calculate characteristic indices such as high calorific value, low calorific value, density, relative density, Huabai number, and combustion potential of different gases in seconds.
Natural gas analyzer GC-7900RFull analysis of oxygen, nitrogen, methane, ethane, propane, isobutane, n-butane, n-pentane, isopentane, and hydrocarbons with C6+or higher in natural gas can be performed in one injection.

The GC-7900R natural gas analyzer is designed as a vertical computer all-in-one machine, which can be used in laboratories or portable.

Key Features:
1. Built in hydrogen generator, high electronic circuit integration,19 inch large screen industrial tablet computer display all-in-one machineGood reliability, simple operation,Ensure stable and reliable instrument quality, capable of long-term uninterrupted operation, which not only guarantees work efficiency but also saves maintenance costs. Automatically memorize operating parameters,Power on does not require resetting.
2. Equipped with a gas cut-off protection system to prevent instrument damage caused by misoperation.
3. The gas path system adopts a high-precision valve structure, which greatly improves the stability of the instrument gas flow rate, thereby obtaining well reproducible analysis results.
4. It can analyze the content of various components such as nitrogen, carbon dioxide, methane, ethane, propane, propylene, isobutane, n-butane, isobutene, n-butene, isopentane, n-pentane, etc. in natural gas and other gases. Content range: 0.01%~100%. Accurately calculate the calorific value, white number, density, etc. of gas by analyzing the content of each component.
5. It can be used in the laboratory or online.
6. The instrument has a unique fully automatic sampling system, which is connected to the outlet of the natural gas detection point to achieve 24-hour unmanned continuous sampling analysis and detection.
7Using the most advanced artificial intelligence software to operate the setting system,The detection data is uploaded to the user control room through the DCS system.
