Explosion proof VOCs online continuous monitoring system/Overview
We have launched an explosion-proof VOCs online continuous monitoring system for key industries in explosion-proof areas. The explosion-proof cabinet used is a positive pressure blowing explosion-proof cabinet, with certificate number CNEx16.0316 and explosion-proof mark ExdeibpzIIBT4Gc.
Explosion proof VOCs online continuous monitoring system/principle
The explosion-proof VOCs online continuous monitoring instrument sampling system extracts the measured gas from the sampling point, passes through the high-temperature sampling probe for dust removal, and enters the online gas chromatograph through the high-temperature tracing pipeline. The chromatograph is equipped with a built-in heating box, which keeps all the pipelines through which the sample passes at high temperature. Then, a high-sensitivity hydrogen flame ionization detector (FID) is used to detect the sample, and finally, data collection, analysis, processing, transmission, and storage are automatically completed through workstation software.
Explosion proof VOCs online continuous monitoring system/feature
-
Adopting positive pressure blowing explosion-proof cabinet
The VOCs online continuous monitoring instrument adopts a positive pressure blowing explosion-proof cabinet, which complies with the GB3836-2010 explosion-proof standard;
