   High accuracy in any length or radius--Whittam rules (rulers/precision scales) are being manufactured with ever increased accuracy since 1860. Graduated rules can be supplied with accuracies of 1/100 mm (0.0004") over 61 cm (24"). Whittam is capable of manufacturing up to 132" long scale sections which can be joined together to any length. The high accuracy is maintained over longer distances by joining the ends ground for butting within .025 mm (.001"). Our Whittam dials or circular scales are accurate to within 18 arc seconds or .00045" on a 10" diameter. We offer circular divided scales and index rings of up to 137 cm (4’6") in diameter.
   Your choice of material, finish and color (with the exception of wood)--the materials used are generally Hardened and Tempered Steel, Bright Mild Steel, Stainless Steel, Brass or Aluminum. We offer matte or polished finishes and a hard chrome plating or electrolyses nickel plating. Graduations can be left open or filled with one of the basic colors of your choice (black being the standard).
   Guaranteed greater durability in hostile
environment
--the engraving (etching with diamond tip tool) process used by Whittam (versus photo etching) ensures greater durability of the markings in a hostile environment and the unmistakable look of quality.
