Rosemount™ Chemiluminescence Detector (CLD)
rosemount cld
Available as an analyzer module to be combined with an MLT analyzer via LON, or as standalone analyzer integrated into a platform.
This detector enables NO or NOx measurements. It is a self-contained unit complete with detector and electronics. The modular design allows for easy system integration. The CLD analyzer module may be a “stand alone” analysis instrument with the addition of our input/output (I/O) module and platform or it can be integrated into a sophisticated multi-component analysis network.
