PEAK GLASS SCALES - GLASS SCALES-S

These control rules have as base a quality transparent glass, 1.7mm thickness for the 1972-Lite series (circular scale), 3mm for the 1972 series and 10mm for the 1972-S series; all have decimal graduation lines engraved through "photo-printing".

The rules allow easy and accurate readings thanks to a 15x lupe (1962) for the 1972-Lite and 1972 series, and two lupes 10x equipped with dioptric regulation and mounted on a carriage to allow an easy slide for the 1972-S series; in this last series the two lupes are used to point on zero and on the final interest point.

This rules are resistent to change of temperature.
