Elcometer 121/4 Standard & Top Paint Inspection Gauges (P.I.G.)

Available in two models, the Elcometer 121 Paint Inspection Gauge (P.I.G.) is designed to measure the paint thickness of single or multiple layers of coatings.

Both P.I.G. models are supplied with illuminated integrated graticule microscopes.

The Paint Inspection Gauge Top model has an internal carousel allowing each of the three cutters to be selected easily together with a cross hatch adhesion tester.

  • Compact and convenient, ideal for paint thickness measurement in confined areas
  • Made of anodised aluminium for durability
  • Bright LED light source for clear vision
  • Top Model can hold one cross hatch cutter & three standard cutters which are locked tight, a simple rotation of the cutter holder changes the cutting tool.
