Available Configurations
RMU1 – Remote Monitoring Unit
Monitors single or double CP coupons and structure bonds. Measures AC and DC parameters and transmits data and GPS location via cellular or satellite networks.
RMU1 + ERP1 – Remote Monitoring with ER Probe Peripheral
Adds high-precision electrical resistance (ER) probe monitoring to an RMU1. Measures metal loss and corrosion growth, with additional probe temperature and probe-to-soil measurement capabilities depending on the connected probe.
RMU1 + INT1 – Remote Monitoring with GPS-Synchronized Interruption
Adds remote, GPS-synchronized interruption for bonds and sacrificial anodes. Supports remotely controlled interruption activities through CorView, helping reduce the need for portable interrupters during close interval surveys.
RMU1-ER – Electrical Resistance Probe Monitor
A dedicated monitoring unit for compatible ER probes. Tracks metal loss and corrosion trends and can also measure ER probe potential when connected to a reference cell.
RMU1-LITE – Pipe-to-Soil Potential Monitor
A cost-effective option for remote pipe-to-soil potential monitoring. Supports instant-off potential measurements and dual-reference-cell validation, making it suitable for high-volume deployments.
RMU1-SUB – Subgrade Remote Monitoring Unit
Designed for demanding underground installations at pipeline test stations. Monitors pipe-to-soil potential, CP coupons and structure bonds, with IP68 ingress protection and an HS-20 load rating.
