blueball.gif (132 bytes) High quality--made with microscopic attention to detail

blueball.gif (132 bytes) 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.

blueball.gif (132 bytes) 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).

blueball.gif (132 bytes) Guaranteed greater durability in hostile
--the engraving (etching) process used by Whittam (versus photoetching) ensures greater durability of the markings in a hostile environment and the unmistakable look of quality.

blueball.gif (132 bytes) Low prices--up to hundreds less than our
competition! Specializing in custom designed
measurement components gives Whittam a
price advantage over the standard ruler and dial manufacturers who are not set up to handle "made to measure" orders and may charge you premiums in setup costs, etc... Our prices can be up to hundreds of dollars less than our competition--give us a try, call us with your specifications today!

blueball.gif (132 bytes) Made to your exact specification--all Whittam
products--horizontal and vertical rules, circular divided scales, straight and circular vernier scales, straight edges, machine dials and index rings are made strictly to customer’s specifications with microscopic attention to detail.
