Fast and Easy Sensor Replacement The SCM4 and ACM4 replacement sensor (RCM4) comes electronically calibrated, and can be purchased directly from your distributor. Simply plug in your new sensor and your SCM4 and ACM4 are automatically calibrated to factory standards. With normal use, the RCM4 lasts for approximately two years. Sensor life is highly dependent on exposure to contaminants, and repeated exposure to contaminants can shorten the life of the sensor.
