DeFelsko - PosiTector RTR H. Digital spring micrometers measure and record surface profile parameters using Testex Press-O-Film™ replica tape.
What is Surface Profile?
Coating performance is related to the profile height on a steel surface. DeFelsko offers three types of devices for measuring peak to valley surface profile height.
Why Surface Profile Measurement is Important
Steel is often abrasive blast cleaned or otherwise roughened prior to painting. The peak-to-valley height of the resultant surface profile is an important factor in the performance of applied protective coatings. Low profile may reduce coating bond strength (adhesion). Too high and the peaks may receive insufficient coverage and possibly rust prematurely. The costly application of more coating may be required if the profile is too high. For these reasons, surface profile should be measured prior to coating application to ensure that it meets contract specifications.
