## ** O2 Combustion Monitor **

Fireye is now offering the CM-420 combustion monitor. The CM-420 works with our existing line of NXCESO2 oxygen probes and provides a touchscreen interface as well as a 4-20mA analog output to indicate the O2 level. Four programmable level alarm relays are also provided. Additional analog inputs for ambient air temperature and an auxiliary device of the user’s choice are provided. All of the information is also available over a Modbus RTU (RS-485) or a Modbus TCP/IP connection.

This panel is housed in a UL508-listed NEMA4/IP65 enclosure.
