RS PRO 30 Piece Surface Roughness Comparator Set Precision Carbon Steel Plates in PVC Wallet 235-7544

RS PRO 235-7544 Surface Roughness Comparator Set is a high-quality 30 piece collection of carbon steel surface finish testers designed to reliably evaluate and compare the surface roughness of machined components.

Each plate measures approximately 3/8 inch by 7/8 inch and is precision engineered to an accuracy within a permitted tolerance of ±12%, ensuring consistent and repeatable tactile surface comparisons.

The plates can be used by scraping a fingernail for tactile sensing or by using a magnifying lens for visual inspection, enabling versatile evaluation techniques for engineers and quality inspectors.

This comprehensive set covers six common machining methods: flat lapping, external grinding, grinding, horizontal milling, vertical milling, and turning, making it suitable for a wide range of surface geometries and workshop applications.

All 30 pieces are neatly stored in a robust PVC wallet that has labelled slots for organization and includes a handy usage guide to aid with correct selection and application.

The RS PRO surface roughness comparators are manufactured from carbon steel, providing durability and the ability to withstand repeated use in demanding industrial, manufacturing, engineering, laboratory, and quality control settings.

The set includes 30 comparator plates for extensive surface finish testing capability. Precision plate dimensions are 3/8 inch by 7/8 inch for consistency across tests. Suitable for six surface machining methods, enhancing versatility.

Delivered in a practical PVC wallet for portability and neat organization. Carbon steel construction ensures durability and longevity.

This set is an essential tool for engineers, technicians, and inspectors who require reliable, accurate evaluation of machined surfaces in industrial manufacturing, quality assurance, and laboratory environments.
