Rosemount™ MLT2 Continuous Gas Analyzer
rosemount mlt2
The MLT 2 analyzer can measure up to five components and the measuring principles may be combined in a variety of combinations.
Configured as a host analyzer to control an extensive measuring system or as a stand-alone unit, it is equipped with an LCD front panel with numerical and graphical measuring value indication. All MLT 2 variations may be equipped with analog and or digital I/Os. The host analyzer I/O is available to all analyzer modules connected within the analyzer network. Upgraded with a CSA-C/US-approved Z purge pressurization system, the MLT 2 can be installed in Division 2 hazardous areas.
