About ROUGHNESS COMPARATOR

These two comparators are specially designed to check the roughness of steel surfaces which have been blast cleaned to cleanliness grades SA 2.5 and SA 3 in preparation for painting.

They conform to ISO 8503.

Versatile Surface Finish Comparator

This device is engineered to provide instant, comparative surface roughness checks across a variety of machining processes, including turning, milling, and grinding. Its sturdy stainless steel construction ensures durability in challenging industrial environments. With twelve precisely machined reference surfaces, users can consistently assess and verify finish standards, making it ideal for both in-house quality assurance and external inspections.

Portable and Easy to Use

Weighing only 170 grams and supplied in a compact protective case, this handheld roughness comparator is designed for portability and straightforward operation. Its manual, visual control mode means it requires no power supply or data interface, and results are obtained instantaneously. The comparator is well-suited for various environments, thanks to its wide temperature and humidity tolerances.

FAQ's of ROUGHNESS COMPARATOR:

Q: How do I use the Roughness Comparator for surface finish assessment?
