LPR Corrosion Sensors vs. Corrosion Coupons
LPR sensors, such as the CR-300, provide affordable and instant corrosion measurement. The LPR level reading represents the real-time electrochemical measurement of corrosion. Measurements gathered from the CR-300 are instant and represent the “real-time conditioning” on an MPY scale based on the metallurgy being assessed.
Description
The CR-300 corrosion rate sensor is ideal for cooling and process water monitoring. In addition to being reliable and affordable the sensor utilizes the linear polarization resistance (LPR) method to produce a raw signal. The raw signal is conditioned, amplified and digitized inside the sensor. Moreover, this avoids interference from the raw signal caused by long distance wiring. Our corrosion sensors measure sample water conductivity directly. Next it also measures for electrochemical noise. The measured noise data is used to calculate an index to quantify the localized corrosion rate also referred to as pitting.
