The Peak Glass Scale consists of a transparent glass plate, which has graduations marked by means of photo-printing. This scale provides accurate readings since it does not screen an object to be measured from the eyes of the user. The glass plate has a function to resist changes because of temperature changes.
The 300S, 500S, 700S and 1000S are supplied with 2 10x, #1983 loupes without scales. The glass scale thickness = 10 mm.
S-type series have two cursors, on both of which Peak scale loupe 10x (without scale) is set. The confirmation of 0-position and measuring between two points are possible.
