Surface Roughness Comparison Set INSIZE ISR-CS130 — reference roughness samples for inspection and calibration

INSIZE ISR-CS130 is a surface roughness comparison set designed to provide standardized reference textures for visual and tactile inspection, verification, and calibration of surface measurement methods. The set contains a range of reference roughness samples that represent common surface finishes used in machining and finishing processes, allowing direct comparison between parts and known references to support quality control and instrument checks.

Advantages

The comparison set offers consistent, repeatable reference surfaces that simplify the assessment of surface texture by sight and touch. It supports faster on-site verification of measurement instruments and inspection procedures without the need for complex equipment. The standardized textures in the set reduce ambiguity when communicating surface quality requirements and help maintain traceable inspection practices in production and maintenance environments.

Suitable for

• Visual and tactile inspection of machined or finished components
• Calibration verification of portable roughness gauges and profilometers
• Quality control and incoming inspection of parts and assemblies
• Operator training in surface finish assessment and specification interpretation

Key specifications

• Range of standardized surface textures representative of common machined and finished surfaces
• Material and hardness suitable for repeated tactile comparison without rapid wear
• Compact set format for bench or portable use in workshop and inspection areas
• Designed for visual and tactile assessment; compatible with handheld roughness gauges and profilometers for verification

How to use

Select the reference sample from the set that most closely matches the suspected finish of the part under inspection. Clean both the reference and the part to remove debris or residues that could affect surface perception. For tactile comparison, run a clean finger or a standardized feeler across the reference and the part to note relative roughness; for visual comparison, examine under consistent lighting and magnification if required. When verifying instruments, place the probe or stylus on the reference surface and compare measured values to expected characteristics or previously recorded instrument responses.

Usage recommendations

Store the set in a dry, dust-free container and handle samples with clean hands or gloves to avoid contamination. Use the set as a complementary reference during instrument calibration and routine inspection; for formal calibration and traceability, follow instrument manufacturer procedures and accredited calibration services. Replace samples if significant wear or surface damage is observed to maintain reliable comparisons.
