Twin-head gage block comparators and universal internal/external comparators are
a vital part of our product line. Gage calibration services, too – either in our
Sub-Millionths Laboratory or on-site at your facility – are yours for the
asking. Why use Edmunds metrology products and services? Our comparators are
considered the "lab standard" by the top metrology laboratories in the world. In
fact, many refer them as the "gold" standard both for their premier quality and
their attractive, metallic gold finish.
Our 20" twin-head gage block comparator answered a great need in the
industry for an ultra-precise comparator that could handle blocks
from 0 to 20" – the full range of a standard set of gage blocks. For
users who don't need the full range, we offer the same benefits in
our smaller comparator for up to 4" blocks. It offers a choice of
readout resolutions as small as .0000001" (one tenth of one
millionth of an inch). Our exclusive step cam allows swift
calibration of Metric or English blocks.
Our Universal Internal/External Comparator is the backbone of many
calibration labs around the world. It's primarily used to calibrate
class X, XX, and XXX master rings and precision parts. It offers a
wide capacity internal measurement range of .040" - 12"; external up
to 11" and superb repeatability and accuracy within .000001".
For our Universal/External Comparators...
Want to check repeatability, calibration and linearity easily? Use
this convenient kit specially made for our universal comparators
which includes a set of three class XXX ring gages.
Our extended range finger sets allow you to measure internal
diameters from .040" (1.00mm) to 13.25" (337mm) To request
