Rosemount™ MLT1 Continuous Gas Analyzer
rosemount mlt1
The compact MLT1 multi-component gas analyzer can measure up to five gas components as a stand-alone analyzer, a system control analyzer with front panel display and keypad or as an analyzer module.
The MLT provides greater installation flexibility and can be configured as a single stand-alone analyzer or as a central interface for multiple analyzer modules with a network board (LON). In addition, it uses FOUNDATION™ Fieldbus communications and has a built in PLC and calculator functionality.
