Micro-Metrics OG214 Plastic Tooke Paint Inspection Gauge

Micro-Metrics’ OG214 Tooke Paint Inspection Gauge for dry film measurement of single or multiple coats on any substrate, as well as the microscopic examination and measurement of substrate and film defects.


SKU: MIC-OG214 Category: Tag:


Micro-Metrics OG214 Tooke Gauge is used to measure directly the thickness of each layer of coating, as well as total coating thickness. A V-shaped groove is made through the paint film and into the substrate. Coating and substrate are observed through a 50-power illuminated magnifier fitted with a measuring scale. Enhanced dual-measure scope features a reticle marked in mills and microns.

The OG214 Tooke Gauge features an injection-molded, high-impact polycarbonate plastic body, suitable for most applications where the gauge will not be exposed to corrosive materials. Precision tungsten-carbide cutting tips are side-mounted with balancing legs to ensure precise alignment of the paint inspection gauge to the surface being examined.
