BGD 548 Paint Inspection Gauge

Product Description

BGD 548 is a paint inspection gauge which is suitable for use wherever conventional electro-magnetic measuring techniques are ineffective, namely for coatings on wood, concrete, plastics and other non-metallic substrates.

Testing with the BGD 548 is based on the standardized wedge cut procedure: The coating is cut through at a defined angle in such a way that the cut penetrates the substrate. The layer thickness (s) is calculated on the basis of the slope projection (b) of the cut face, determined using a measuring microscope, and the cutting angle (α). Similarly, the individual layer thickness of multilayer systems can be ascertained.


ASTM D 4138 and AS 1580 Meth 408.1

Technical Specification

The BGD 548 consists of a black painted aluminium block which accommodates the following functional elements:

  • Exchangeable carbide tip with precision-ground angular cutting blade (4 cutters included)
