Tooke Paint Inspection Gage

Available in in two styles:
  • rectangular configuration made of machined aluminum (OG202)
  • rectangular configuration made of molded polycarbonate plastic (OG204)

Both versions of the Paint Gage come in a case with strap, spare batteries and bulb, hex wrench and a technical data sheet. Standard cutting tips are 1×, 2×, and 10×. An optional 5× tip is available. Also, a gage can be ordered with three tips of the same size.

OG202 A precision tool (single picture of gage, 15 kB) for inspection and thickness measurement (in accordance with ASTM D4138) of single or multiple coats on any substrate, and for microscopic observation and measurement of substrate and film defects. Uses illuminated 50-power microscope with measuring reticle, and mounts tungsten carbide cutting tips for precise incision of the work surface.
OG-204 This less-expensive gage (single picture of gage, 12 kB) is identical to the OG202 Tooke Paint Inspection Gage, but made of molded polycarbonate plastic.


MG-402 Microgroover

The Micro-Metrics Microgroover (single picture of gage and positioning block, 11 kB) is a high-speed rotary tool for creating the small, almost microscopic, incisions required for measurements with the Tooke Paint Inspection Gage. Especially effective on hard and brittle (concrete) materials, as well as soft or elastomeric (rubber) substances, this tool eliminates the deformations of coating and substrate that may occur when conventional gage cutting tips are used. Hard, brittle, tough, fibrous, tender, or elastomeric materials exhibit clean, non-tearing, controlled disintegration under the rotary cutter. The high-speed cutter “erodes” away surface material in a precise pattern, leaving adjacent and underlying areas undisturbed. In addition to film thickness measurements, small-scale operations of cutting, grinding, sawing, and polishing can be performed with this useful cordless power tool.


H501 Pencil Hardness Gage

The Pencil Hardness Gage (single picture of gage and dressing disk, 17 kB) permanently holds all pencil leads in the configuration required to perform the ASTM D3363 Pencil Hardness Test, which is the simplest and most generally accepted paint film hardness test. (Under ASTM D3363, pencil leads of known hardness are used to evaluate paint film hardness. Pencil hardness is a traditional test for gaging the hardness and scratch resistance of a coating by simply scratching a part or test panel with a pencil lead of known hardness.)


S-701 and S-701 Film Thickness Standards

The Film Thickness Standards (single picture of S-702 and case, 20 kB) are supplied in thickness ranges of 1-10 mils (S-701) or 10-60 mils (S-702) in non-certified grades. They are packaged in sets of six pieces in a calling-card-sized plastic folder. Essential for performance verification of indirect (magnetic or eddy current) type gages and micrometers, and for precision comparison with Paint Inspection Gage results.
