Keane-Tator Surface Profile Comparator with handheld illuminated magnifier and two star-shaped surface comparison discs.

Keane-Tator Surface Profile Comparator Gauge

Manufactured by Neurtek

Ideal for coating inspectors and surface preparation professionals, this compact and durable surface profile comparator gauge is used to determine the surface profile of blast-cleaned surfaces.

It covers sand, shot, and grit surface profiles, offering quick, precise and versatile surface evaluation, as well as dual-mode inspection (visual and tactile).

Using an illuminated 5X magnifier and reference disc, the comparator helps determine whether the surface profile meets the required specifications before painting or coating.

Benefits

  • Allows for quick, reliable comparison of blasted surfaces with standardised roughness levels.
  • Compact and rugged for field use.
  • Conforms to ASTM D4417.
  • Ensures consistent preparation before coating.
  • Five different grades of roughness in each comparator.
  • Includes a 5X magnifier and vinyl case.

How Does The Surface Profile Comparator Work?

Visual Method:

  1. Place the disc beneath the magnifier.
  2. Position the magnifier on the blast-cleaned surface.
  3. Visually compare the surface texture with the disc’s segments.
  4. Use the “V” markers between sections for greater accuracy.

Tactile Method:

  1. Touch the blasted surface with your fingertip or a soft wooden pencil.
  2. Compare the tactile feel with the disc segments to determine the profile depth.

What’s Included?

  • High-purity nickel electroformed reference disc.
  • 5X illuminated magnifier for detailed inspection.
  • Vinyl case for protection and portability.

Each reference disc is a precise copy of a master disc, duplicated within ±50 microinches, and is available for sand (S), shot (SH), or grit/slag (G/S) blasted surfaces.
