MSA Ultima X

X3 Technology brings multi-sensing and Modbus output to the ULTIMA X series gas monitors. The technology allows three sensors of any combination of electrochemical, catalytic and infrared type to be connected to one ULTIMA X3 series gas monitor. Each sensor can be remote from the gas monitor. All the features of the ULTIMA X such as sensor disconnect under power, LCD, status LEDs and relay output are also included.
