Description
Product Overview
The K1190VK Surface Roughness Comparator Set is a comprehensive engineering tool designed for precise surface finish evaluation. It includes 30 composite gauge samples covering a wide range of Ra values, three flat grinding standards (2, 4, and 6 µm), and a compact wallet‑size case measuring approximately 6″ × 3″ × 3/8″. Constructed from durable composite material, each gauge provides a true, repeatable representation of common surface textures found in machining and manufacturing. The lightweight design (≈14 oz) ensures easy transport between workstations or field locations.

Usage
Ideal for quality control engineers, machinists, and maintenance technicians, this set enables quick visual comparison of workpiece surfaces against calibrated standards. Use the gauges with the naked eye for a rapid check or pair them with a microscope for detailed analysis. The set is perfect for routine inspections on CNC‑machined parts, injection‑molded components, and any metalworking application where surface texture impacts performance or fit. Its portable case allows on‑site use in production floors, clean rooms, or field service environments.

FAQ
What surface finish ranges are included?
The set provides samples for six Ra ranges, typically from fine mirror finishes up to coarse machining marks, allowing coverage of most industrial applications.
Can the gauges be used with a microscope?
Yes, the composite samples are designed for both naked‑eye comparison and microscope examination, giving you flexibility for detailed analysis.
How durable are the gauges?
Each gauge is made from high‑quality composite material that resists wear and maintains dimensional stability even after repeated use.
Is the case water‑resistant?
The case is constructed from sturdy polymer with a tight‑fit lid, offering protection against splashes and dust, but it is not fully waterproof.
Do you offer calibration services?
We provide calibration verification and can supply replacement gauges if any sample falls out of tolerance.
