The Peak Glass Scale consists of a transparent glass plate, which has graduations marked by means of photo-printing. This scale provides accurate readings without screening a whole visual field of an object to be measured from the eyes of the user. This glass plate has a function to resists against the difference of temperature.
For easier readings, use the accessory, Peak Lupe 15X. S-type series have two cursors, on both of which Peak Scale Lupe 10X (w/out scale) is set. The confirmation of 0-position and measuring between two points are possible.
Scales "1972" series have a thickness of 3 mm, while scales "1972 S" series have a thickness of 10 mm.
