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?") in diameter.

Certificate of Calibration
Unlike our competition, we do not issue Certificates
of Calibration. They are issued by in independent accredited
laboratory regulated by NIST and therefore their accuracy is fully
verifiable. |
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.
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

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!
