    Loupes with Measuring Scale

    Image of Product. Front orientation. Magnifiers. Loupes with Measuring Scale.
    Magnify and measure in one operation. Two lenses provide distortion-free viewing. This loupe includes a general purpose scale that measures circles from 0.002" to 0.0625"; radii from 1/16" to 3/8"; angles up to 90° in 5° increments; lengths up to 0.5" in 0.005" increments; lengths up to 10 mm in 0.2 mm increments; and line widths from 0.016" to 0.250".

    Radii

    Style B

    Measure the radius of curves on tools, patterns, and dies. These gauges are small enough to carry around.
    Style B—Use style B as a radius gauge, diameter gauge, and ruler. They check for convex radii. Made of stainless steel, they resist corrosion.
