RKI M2A Series Stand Alone Explosion Proof Transmitter

The RKI M2A Series Stand Alone Explosion Proof Transmitter provides the best in gas detection. Featuring a direct read-out and versatility with the option to function independently or as a part of an integrated system, the M2A series is a powerful tool for any jobsite with gas detection and transmission needs. The M2A sensor/transmitters can connect to virtually any controller, PLC, or DCS and are designed to work with the RKI Beacon 110, Beacon 200, Beacon 410, or Beacon 800 Controllers. Set-up and operation of the M2A series monitors is simple, and the system utilizes a magnetic wand technique for performing calibration without opening up the sealed housing. Because the unit does not need to be opened for zeroing or calibration, it is not necessary to declassify the surrounding area to perform routine maintenance.

Applications: Petrochemical plants, Refineries, Water & wastewater treatment plants, Pulp & paper mills, Manufacturing facilities, Automotive, Semiconductor plants, Chemical plants
