Place the microfinish comparator surface roughness scale alongside your work piece
Slide the scale so that the rectangle with the surface roughness you want is adjacent to the piece you are examining
Compare by drawing the tip of the fingernail across each surface at right angles to the tool mark
The feel of the fingernail contact must be the same if the finishes are identical
There are nine replicated cast surface finish specimens ranging from 20 to 900 microinches
The C-9 cast microfinish comparator is rectangular in shape (4 1/2"x 3 1/4") and is a corrosion resistant electroformed nickel duplicate of actual cast surfaces
Supplied in a leatherette case with engineering data and instructions

How to Choose the Best Surface Roughness Comparators
Key Factors for Choosing a Surface Roughness Comparator
When selecting a surface roughness comparator, consider the following key factors to ensure it meets your specific needs:
Material and Durability: Comparators are often made from metal or durable plastic. Metal comparators, typically stainless steel, offer superior longevity and resistance to wear, making them ideal for frequent or harsh industrial environments. Plastic comparators can be more cost-effective and suitable for less demanding applications or educational purposes.
Roughness Range and Units: Ensure the comparator set covers the range of surface roughness values you commonly work with. Check if the units (e.g., microinches [μin] or micrometers [μm]) align with your industry standards and measurement tools. A broader range provides greater versatility for various inspection tasks.
Included Standards and Certification: Verify the number and types of surface finishes included in the set. Reputable comparators often come with certifications or traceable standards, guaranteeing accuracy and consistency. This is particularly important for quality-critical applications where precise replication of standards is necessary.
Frequently Asked Questions
What is a surface roughness comparator?
A surface roughness comparator is a tool used to visually and tactilely assess the finish of a surface. It typically consists of a set of standardized samples with known roughness values, allowing for direct comparison with a workpiece.
How do I use a surface roughness comparator?
To use a comparator, you compare the surface of your workpiece to the samples provided. This can be done by visual inspection under good lighting or by tactile comparison, feeling the texture of the samples against your surface.
What are the common units of surface roughness?
The most common units for surface roughness are micrometers (u03bcm) and microinches (u03bcin). Both are measures of the average height of the surface irregularities within a specified sampling length.
How often should I replace my comparator?
The lifespan of a comparator depends on its material and how frequently it's used. Metal comparators are generally more durable than plastic ones. Regularly inspect your comparator for signs of wear or damage that could affect comparison accuracy.
