Acuity CR

Autonomous corrosion monitoring in accelerated test chambers and outdoor exposure fixtures

The Acuity CR System Enhances Corrosion Test Methods to Improve Confidence

For corrosion testing of coatings and materials in accelerated environments, Acuity CR increases confidence when assessing the protective properties of coatings and when determining the corrosion performance of engineering alloys by using sensorized test panels that autonomously record corrosion rates and environment severity.

The systems continuously collect air temperature, relative humidity (RH), surface contaminants, free corrosion of alloys, and galvanic corrosion of different materials.

Acuity CR Benefits

Expedite testing and qualification

When introducing new coatings into service, accelerate testing times with continuous and quantified measurements of performance

Increase confidence in predicted performance​

Continuously record the environmental conditions that drive corrosion during accelerated and outdoor tests to enhance confidence when interpreting results

Determine Severity Classification

Determine the cumulative severity of any environmental exposure using a common metric

Enhance Understanding of Materials Selection

Galvanic corrosion sensors of user-defined engineering materials provide a direct measure of corrosion performance in the field or during testing (CFRP, Aluminum Alloy, Titanium, Steel, and more)

Isolate factors causing corrosion

Autonomous measurements of corrosion rates paired with environmental sensors to isolate the factors causing corrosion and capture when corrosion damage occurs
