Room CO Transmitter
Description
The model MCM700 carbon monoxide transmitter utilizes a electrochemical sensor, unlikely other traditional sensors, which has no interferences by other gases. This ensure to make sensor long-term stability and maintenance-free operation for a long period. MCM700 series a proton conductor carbon monoxide (CO)sensor that utilizes short-circuit as a sensor signal. The basic components of gas sensing layer are a working electrode, and proton-conducting membrane in between them.
MCM700 constantly measures the carbon monoxide’s concentration its range up to 0 to 1000 ppm in the ventilation systems, parking lot and boiler room. Its measurement range of 0 – 1000 ppm covers the range required to monitor compliance with ASHRAE or other ventilation standards. Packaged in a compact, distinctively styled engineered ABS plastic enclosure, the MCM700 can be discretely installed anywhere from boiler room to underground parking lot.
The model MCM700 provides several outputs alternatively. A 4-20 mA or 0-10 VDC output and Modbus RTU communication protocol are standard. An optional LED readout is available . An optional two relay contacts and alarm setting can be configured by the program. A simple one point calibration procedure and a built-in programmable port that makes the model MCM700 simple to maintain with a long life-span.
