2Nakatsugawa Plant Dedicated to the Manufacture of Sensors
The Nakatsugawa Plant was established in 1997 as the twelfth Mitutoyo
plant in Japan and is located in a beautiful natural environment within
the central industrial complex of Nakatsugawa City, Gifu Prefecture.
It is dedicated to sensor manufacture and incorporates an integrated
production system from design to manufacture of measuring instruments
such as dial gages, test indicators, digimatic indicators and bore gages.
Leading-edge production technologies and facilities ensure that the
Mitutoyo-brand instruments shipped from here are highly valued as theworld's best, providing users with a strong feeling of confidence.

prolonged use(Design registered in Japan)

The new carbide-ball contact point and anvil tip haveincreased abrasion resistance compared with the steelball type and better surface roughness compared with themolded carbide-tip type. Thus, they almost never scratch aworkpiece.

This model reduces the influence of heat from the operator’s
hand by 50% by increasing the grip size and making the grip
hollow-structured, thereby retaining high-accuracy measurement.

Carbide ball
The length below the grip is the same as that of the old model.
This guarantees no difference in operability of the gage.
(Note: The overall length of this model is longer than that of its predecessor
and therefore may not fit in an existing custom-made storage box.)
