Roxar™ Retrievable Electrical Resistance (ER) Probes
Roxar Retrievable ER Probes
The Roxar Retrievable Electrical Resistance (ER) Probe is a reliable tool for monitoring internal corrosion in common environments such as oil, gas and water.
The ER probes are designed to be installed in high pressure pipelines and is compatible with hydraulic and mechanical access fittings. When used with the Roxar transmitter and Roxar Fieldwatch, the many designs provide highly accurate readings. The Roxar ER Probes provide sensitive and fast responses to corrosion change, leading to extended equipment life and increased flow assurance.
