TCD-500 thermal
conductivity hydrogen analyzer works by taking advantage of the
difference between |
|
the thermal conductivity
coefficient of the component to be analyzed and the background
component, |
|
and the characteristic that the
thermal conductivity of the mixed gas changes with the change of the
|
|
analysis component. The online
analyzer composed of thermal conductivity gas sensor and intelligent
|
|
signal converter has the
characteristics of wide range of data to be measured, good stability and
short |
|
response time, TCD-500 thermal
conductivity hydrogen analyzer is used for automatic analysis of |
|
hydrogen content in
non-explosion-proof occasions. This instrument is applicable to online
analysis of |
|
hydrogen content in the
production process of fertilizer plants, generator cooling units,
cracking gas |
|
and other industries. |
