A precision tool for inspection and dry-film 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. The Tooke Paint Inspection Gage uses an illuminated 50-power microscope equipped with a “universal scope” with a measuring reticle that accommodates measurement in mils, microns, and millimeters; and mounts tungsten carbide cutting tips for precise incision of the work surface. Standard cutting tips are 1X, 2X, and 10X. An optional 5X tip is available.
Holds eight (of fourteen provided) 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.For catalogue press HERE
The Microgroover is a high-speed rotary tool for creating the small, almost microscopic, incisions required for measurements with the Tooke Paint Inspection Gage. This technique eliminates the deformations of coating and substrate which may occur when conventional gauge 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.
