Description
The RKI Instruments M2A-XL gas transmitter operates as a stand alone gas monitor or as part of an integrated system. It connects to any controller, PLC, or DCS with an analog or digital signal. It can be calibrated externally with a magnetic wand, avoiding the need to open the housing and declassify an area for routine maintenance. Automatic zero drift correction compensates for aging sensors and ensures stable readings.
Sensor construction is rated Class I, Div 1 Groups B, C, D for flammables, CO, H2S, O2, and CO2, and Class I, Div 2 for all other toxics. Toxic sensors are electrochemical type plug-in sensors, providing high specificity, fast response, and a long life. Their plug-in design allows quick replacement in the field without tools. Sensors are available for NH3, SO2, PH3, AsH3, and HCN.
Applications for the RKI Instruments M2A-XL include petrochemical plants, refineries, water and wastewater treatment plants, pulp and paper mills, manufacturing facilities, automotive, semiconductor and chemical plants.
