Mitutoyo MDH High Accuracy Digimatic Micrometer
The Mitutoyo MDH Digimatic ABSOLUTE digital micrometer provides fast and easy high-accuracy measurements on workpieces that require absolute precision. Exceptional performance is achieved due to the MDH’s highly rigid frame, high performing constant-force ratchet mechanism and innovative thread cutting technology in the spindle. Delivering +/-0.5μm accuracy at 0.1μm resolution means Mitutoyo's MDH is one of the most accurate hand-held micrometers available, and this instrument will enable you to easily and rapidly measure workpieces that require very-high-accuracy measurement. This remarkable performance is attained due to Mitutoyo's proprietary ABS (absolute) rotary encoder and high-accuracy thread cutting technology.
Please see Data Sheet in Documents Section for additional specifications/technical data.
Technology of the MDH Micrometer:
- ABS (Absolute) rotary encoder with a resolution of 0.1µm and high-accuracy thread cutting technology - The development of a 5000-division rotary encoder has achieved the unprecedented resolution of 0.1 μm in a hand-held micrometer. The commercialization of this ABS (absolute) encoder also improves its reliability. Additionally, since the spindle-thread pitch accuracy directly affects measuring accuracy, Mitutoyo has developed a series of technologies from thread cutting technology to thread evaluation technology, thereby guaranteeing the achievement of high accuracy.
- Ratchet thimble with an anti-friction bearing - Measurement repeatability has been improved by changing from sliding to rolling friction to dramatically reduce the torque needed to operate the constant-force device. This makes measurement even more consistent even for operators new to this micrometer.
- Heat transfer reduction with a heat shield - The influence of heat transferred to the micrometer frame during measurement through hands has been reduced with this micrometer by fitting the supplied heat shield.
- Applications of MDH Include:
- Manufacturing - pin gage and gap gage calibration
- Medical care - hypodermic needle, implant, catheter measurement
- Electronics - fiber optics and optical film measurement
- Automotive - gear tooth, bearing measurement
Mitutoyo MDH High Accuracy Digimatic Micrometer Features:
- Available in Metric and Inch/Metric models
- Enabling .000005in / 0.1μm resolution measurement, the MDH micrometer is ideal for customers who need to make highly accurate measurements with a hand-held tool
- A highly rigid frame and high-performance constant-force mechanism (Patent pending) enable more stable measurements , while the clicks emitted when the work piece is being measured assure the operator that measurement is proceeding normally
- 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
- The ABS (Absolute) rotary sensor also eliminates the need to perform origin setting every time the power is turned on, offering immediate measurement
- With no possibility of over speed errors, the MDH High-Accuracy Digimatic Micrometer also delivers a high level of reliability
- The 3.2mm wear resistant carbide tip on the measuring face allows for accurate measurements over an extended period
- Function of the MDH include: Preset, Zero-Setting (INC measurement system), Hold, Resolution Switching, Function Lock, ON/OFF, Auto Power Off, Measurement Data Output, Error Alarm
- The built-in Hold function freezes the displayed value, enabling the micrometer to be removed from a workpiece for better viewing when the readout is not easily visible
