Faced with the inability to meet corrosion and salt spray testing requirements, they needed some answers quickly. Their customer, a large OEM, required 96 hours of ASTM B-117 salt spray protection on bare steel tubing.

The heart of any electromagnetic measurement system is the probe. The probe is a very complex system, which performs the conversion of the appropriate measurement method to a reading on the corresponding gauge. Proper selection of the coating thickness instrument and probe will determine the accuracy and reliability of the measurement results. Addressing each factor is critical to providing accurate results for complex challenges faced by coatings professionals each day.

Curvature Compensation:
One of the most common influences on coating thickness is curvature. A curved part can cause erroneous readings without proper adjustment of the gauge and probe.
