SMC4 Remote Telemetry Unit
The SMC4 is a remote telemetry unit, developed
specifically for the cathodic protection industry, with the
resources required for advanced status and control applications.
With automatic reporting of routine measurements and significant
events, SMC4 benefits users by reducing or eliminating field travel.
In addition, multiple rectifier synchronized interruption can
easily be achieved through the use of the GPS timing utilities.

Production of SMC4 units is currently being phased out in favor of RMU5, the next generation product in the corTalk® line.
