Broadening the Abilities of the Surface Analyst
The Surface Analyst™ has the unique ability to measure on almost any surface: vertical, horizontal, smooth, rough, mirrored and in an easy, accurate, fast, and non-destructive way. However, until now, measuring on concave and convex surfaces presented an obstacle. Now BTG Labs’ Surface Analyst boasts a new specialized head for measuring on concave and convex surfaces.
Before, the only way to measure on these surfaces was with a benchtop goniometer which can only measure on flat or convex materials. Goniometers measure contact angle from a horizontal view. However, a concave material prevents visual of the horizon line needed to determine the contact angle. The closest one could get to measuring a concave surface was to use a flat coupon of the same material. While this would offer insight to the surface energy of the material, it would not be exact because it would not be the actual concave part, thus allowing for guesswork. …Read More
