L.P.R. Extractable probe
Linear Polarization Resistance (LPR) probe is composed of three electrodes (Working Electrode, Counter Electrode and Reference Electrode) and when it is connected to the AE-Corr-Meter it gives instantaneous corrosion rate not affected by solution resistance.
It has a threaded or flanged Packing Gland connected to a Ball Valve.
Insertion and extraction (for a scheduled “program of replacement” while the plant is working) can be done without using any other tools; Safety Clamps can be provided to increase safety
Electrodes of different shapes are suitable, depending on monitoring condition:
Protruding Electrodes (for instantaneous reading, specially designed for water treatment plants).
Tubular Electrodes (for periodically or continuous monitoring of a pipeline or of petrochemical plant).
Using LPR extractable probe it is possible to insert the probe following a “measuring program” and to retrieve it when is haven’t to be used or for the replacement while the plant.
