Roxar™ Retrievable Linear Polarization Resistance (LPR) Probes
Roxar Retrievable LPR Probes
Roxar Retrievable Linear Polarization Resistance (LPR) Probe is an accurate and reliable instrument that measure real time corrosion rates in water systems.
The corrosion rate calculation is based on measuring the current response to a small polarization (10 - 20 mV) to a steel electrode’s corrosion potential. The instant response also makes the LPR Probe suitable for fast detection of oxygen ingress into systems that are assumed to be oxygen free, such as water injection systems to sustain pipeline and asset integrity. The Roxar Retrievable LPR Probe can be used in both hydraulic and mechanical access fitting systems.
