The RKI M2 series Fixed Gas Sensor/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 M2 series is a powerful tool for any jobsite with gas detection and transmission needs.

The M2 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 M2 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.

Key Features:
  • Independent, stand-alone fixed gas monitor system
  • Connects to virtually any controller, PLC, or DCS
  • Non-intrusive magnetic calibration
  • 4-20 mA and Modbus digital outputs
  • High specificity
  • Long life sensors
  • Fast response
  • Direct readout on backlit LED screen and can be transmit to controller
  • Available gases include LEL, H2S, CO, PPM HC, & CO2
  • Toxic gases include Cl2, NH3, SO2, HCN, and more
  • Infrared sensor for combustibles and CO2

    Can I get cut sheets on RKI M2 gas sensor.
    Does it need to be field calibrated?

      Here’s a link to the data sheet: http://www.rkiinstruments.com/pdf/M2.pdf<br>
      <br>
      Like all gas monitors, the M2 does need to be calibrated. It can be calibrated in the field, and because it doesn’t have to be opened for zeroing or adjustment, it’s not necessary to shut down and declassify the area for maintenance.
