Rosemount™ MLT4 Continuous Gas Analyzers

Rosemount

Housed in a 19"  rack enclosure, the MLT4 is a multi-component gas analyzer that can measure up to five components simultaneosly and features NDIR / UV / VIS photometer, paramagnetic and electrochemical O2, and thermal conductivity sensors. 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.
