Has a clear acrylic stand that allows ambient light illumination of object and graticule. Provided with spiral twist mechanism for precision focusing, and a focus lock ring. Ideal for engineering applications like checking small parts, linear measurements, angles, hole diameters, thread size and thickness. With the appropriate graticule it is an invaluable aid as graphic arts comparator for type, spacing and size. Also useful for proof reading and editing, aerial photo checking and geological sand checking. A choice of fifteen different graticules is available for varied applications.
