Second level can effectively avoid small of desiccant magnesium perchlorate except water filter 32 is by the way of lower end air inlet, upper end outlet
Grain etc. is mixed under test gas, in addition, second level dust removal filter 42 is added in the gas circuit lower end in flow controller 52, it can be effective
Enhance its dust removal and filtration effect, molecule avoided to reduce the deposition of other substances in infrared pond 6 to the damage of aspiration pump 7 etc.,
In turn, the accuracy for effectively increasing its measurement result substantially prolongs its service life；Meanwhile it being removed by adding the second level
Dirt filter 42, further elongation aspiration pump increase its buffering capacity, eliminate infrared sulfur measuring instrument at a distance from flow controller
The liquefaction phenomenon of minor amount of water in pipe-line system, and then the metal parts in pipeline is avoided to get rusty, additionally due to buffering capacity
Increase, gas flow regulation device is more stable, in turn, improves the accuracy of its measurement result to a certain extent.
Finally, being not intended to limit the scope of the present invention the above is only preferred embodiment of the invention.It is all this
Within the spirit and principle of invention, any modification, equivalent replacement, improvement and so on should be included in protection model of the invention
Within enclosing.
