  • Functionally and electronically identical to the OMA-300 UV-VIS, the solid state OMA-406R is designed to be rack-mounted. This turn-key unit fits a standard 19" rack, providing typical OMA outputs including 4-20mA, RS232, and Modbus (TCP/IP, Ethernet, serial).

    The OMA-406R is often more suitable for laboratory environments but is occasionally installed in shelters in the field. This system can be used with any AAI flow cell and/or sampling system.
  • Simply a rack-mounted version of the OMA-300 UV-VIS, the OMA-406R is designed for virtually all of the same applications. AAI engineers know that each process has highly specific needs, so we made our product line versatile and our instruments primed for integration.
