High-Accuracy
Digimatic Micrometer
The world’s first 0.1μm micrometer
(Based on Mitutoyo's data valid as of June 2011.)

0.0001mm
Resolution

•Enabling 0.1μm resolution measurement, this micrometer
is ideal for customers who need to make highly accurate
measurements with a hand-held tool.
•The High-Accuracy Digimatic Micrometer utilizes Mitutoyo’s
innovative 0.1μm resolution ABS (absolute) rotary sensor*1
and high-accuracy screw machining technology to reduce
the instrumental error to ±0.5μm, delivering higher
accuracy without sacrificing operability.

•The ABS (absolute) rotary sensor*3 eliminates the need
to perform origin setting each time
the power is turned on, letting you
start measuring straight away. With no
possibility of overspeed errors, the High-Accuracy Digimatic
Micrometer also delivers a higher level of reliability.

*1. Patent pending in Japan, the United States of America, the European
Union, and China.

•The High-Accuracy Digimatic Micrometer has a range
of features to enable flexible measurement, including
switchable resolution (0.0001mm/0.0005mm), function
lock and preset.

•A highly rigid frame and high-performance constant-force
mechanism*2 enable more stable measurement, while the
clicks emitted while the workpiece is being measured assures
the operator that measurement is proceeding normally.

*3. Patent pending in Japan, the United States of America, the European
Union, and China.

*2. Patent pending in Japan, the United States of America, the European
Union, and China.

•Body heat transferred to the instrument is reduced by
a (removable) heat shield, minimizing the error caused
by thermal expansion of the frame when performing
handheld measurements.
