RCM4 is a field replaceable carbon monoxide sensor for the Fieldpiece SCM4 carbon monoxide detector and ACM4 carbon monoxide accessory head. It comes already electronically calibrated and is easy to replace. You simply plug the new sensor into the SCM4 or ACM4 and they are automatically calibrated to factory standards. The RCM4 will last for approximately 2 years under normal use. The sensor life is highly dependent on exposure to contaminants, and repeated exposure to contaminants can shorten the life of the sensor.
