L.P.R. Fixed Probe
Linear Polarization Resistance (LPR) Probe is made by three electrodes (Working Electrode, Counter Electrode and Reference Electrode) and when it is connected to the AE-Corr-meter it gives instantaneous corrosion rate unaffected by solution resistance.
Electrodes of different shapes are suitable, depending on monitoring condition:
Protruding Electrodes (for instantaneous reading, specially designed for water treatment plants).
Tubular Electrodes (for periodical or continuous monitoring of a pipeline or of a petrochemical plant).
LPR fixed probe is permanently immersed in the fluid, and its replacement is possible only when the plant is not working.
