Pyxis—CR-300 Wired Corrosion Rate Sensor

March 29, 2022 – The Woodlands, TX – LPR corrosion rate monitoring is a valuable tool that can be easily and affordably deployed to provide both general and localized corrosion measurements instantly. There is a common industrial misnomer that the use of inline LPR corrosion sensors should be identical to corrosion coupons. The LPR Corrosion level represents the real-time electrochemical measurement of corrosion.

The CR-300 corrosion rate sensor is ideal for cooling and process water treatment.  The sensor utilizes the linear polarization resistance (LPR) method to produce a raw signal. The raw signal is conditioned, amplified and digitized directly in the sensor itself.  Corrosion sensors measure sample water conductivity directly and compensate for the conductivity. These unique product characteristics make the Pyxis Lab® LPR superior in performance and accuracy. In addition to the LPR measurement used to obtain the general corrosion rate, the CR-300 sensor also measure for electrochemical noise. The measured noise data is used to calculate an index to quantify the localized corrosion rate also referred to as pitting.
