Description
Condition
Used (Well Used / Flawless Function).
This dial indicator is in “well used” condition, showing cosmetic signs of workshop service similar to the previous units. It has been tested and works flawlessly. The spindle moves freely, and the mechanism is crisp. Configuration Note: Although the model number “S” typically denotes a lug back, this unit is currently fitted with a Flat Back plate, making it consistent with the previous indicators and ideal for mounting in bore gauges or fixtures where space is limited.
Product Overview
The Mitutoyo 2901S-10 is a high-precision “One Revolution” dial indicator. Unlike the previous 2046 models (which read in 0.01mm), this instrument features a much finer graduation of 0.001mm (1 micron).
It is designed for high-tolerance inspection where “close enough” isn’t good enough. The “One Revolution” mechanism limits the measuring range to 0.16mm, effectively preventing the operator from making reading errors by miscounting spindle revolutions. If the needle moves, you are seeing the absolute deviation. The dial is balanced (80-0-80) to clearly show positive and negative variance from the zero point. It also features Mitutoyo’s shock-proofing mechanism to protect the sensitive 1-micron movement.
Brand Information
Mitutoyo Corporation (est. 1934) is the global leader in precision metrology. The Series 2 “One Revolution” indicators are the gold standard for quality control. This specific model is the upgrade path for machinists who need to hold tolerances tighter than +/- 0.01mm.
