EN-630 Type CO2 AnalyzerDetailed product description：

The EN-630 thermal conductivity gas analyzer is a physical analyzer that can be used to analyze the content of a certain component (referred to as the test component) in a gas mixture. It applies the physical property of changes in the content of the component to be tested in a gas mixture. The change in thermal conductivity leads to a change in the resistance value of the hot wire, indirectly determining the content of the component to be tested. In the process of heat conduction, different solids have different thermal conductivity coefficients, resulting in different rates of heat conduction. Those with higher thermal conductivity coefficients transfer heat faster, while those with lower thermal conductivity transfer heat slower. Gases, like solids, can conduct heat, and the speed of heat transfer is also related to the thermal conductivity of various gases. So the EN-630CO2 analyzer works based on this principle. The instrument adopts a stable and reliable thermal conductivity gas sensor and microprocessor technology, with functions such as large screen LCD display, upper and lower limit alarm, standard signal output, and relay contact alarm output. Used for measuring carbon dioxide concentration, it is also suitable for online gas analysis in industrial production and other analytical applications.
