GC-8850 Gas Calorific Value Analyzer for Natural Gas and Fuel Gas
Testing
GC-8850 is a portable automatic gas analyzer based on the GC- TCD
principle. The analysis system is heated to a high temperature
state and separated by a chromatographic column. It can measure
nitrogen, methane, ethane, propane, butane, carbon dioxide and
other components , and calculate the gas calorific value, density,
molecular weight, gasification rate and other indicators . The
analyzer has a built-in sampling diaphragm pump for automatic
sampling. The instrument can adjust the analysis system and set the
chromatographic software as needed to measure the content of the
specified type of gas. In addition to the above components ,
oxygen, carbon monoxide, isobutane, n-butane, isopentane, n-pentane
and C6+ specified gas components can also be measured. GC-8850
provides the best solution for gas detection.
8- inch color touch screen, rich and intuitive display content;
Small size, light weight, easy to carry, can be tested anytime and
anywhere;
The machine integrates analytical column, detector, working
software and computer. The fully automatic operation is suitable for both on-line detection of industrial pipelines and
airbag sampling analysis in laboratories;
Three- dimensional heating, more uniform heating and small temperature gradient;
Dual-channel data acquisition card to meet the needs of different
users and reserve expansion space;
The calorific value working software automatically calculates the
content of the detected gas components, as well as related indicators such as high calorific value, low calorific value, density,
relative density , and gasification rate .
Built-in diaphragm sampling pump to avoid detection errors caused by squeezing the bladder by hand;
One-touch start, fully automatic operation; the electric injection valve avoids detection errors caused by uneven force of the manual valve,
thereby improving the repeatability of the test results;
Can be equipped with mouse and keyboard for more convenient operation;
