Concrete structure thickness gauge Model 455

plasticpaintcoating

Description The P.I.G. 455 is a paint inspection gauge suitable where conventional electromagnetic measuring techniques are ineffective, specifically for coatings on wood, concrete, plastics and other non-metallic substrates.

Testing Principle Testing with the P.I.G. 455 is based on the standardised wedge-cut procedure: the coating is cut at a defined angle through to the substrate. Layer thickness (s) is calculated from the slope projection (b) of the cut face measured with a measuring microscope and the cutting angle (α). Individual layer thicknesses in multilayer systems can also be determined.

Design and Function The P.I.G. 455 consists of a black-painted aluminium block incorporating the following functional elements:

• Exchangeable carbide tip with precision-ground angular cutting blade.
• Measuring microscope with 50× magnification and a reticle (2 mm with 1/100 division), also suitable for inspection tasks.
• Two pairs of support pins to hold the measuring microscope securely and guide the carbide tip.
• Battery compartment for two AA (mignon) batteries.
• Combination of LED and fibre-optic light guide for optimum specimen illumination at low current consumption.
• Key for the integrated illumination.
