MITUTOYO - High-Accuracy Digimatic Micrometer MDH-25MB| JSR GROUP

 Manufacturing

Pin gage measurement

Pin gages are widely used for measurement of the diameter or center-to-center distance of holes. The periodic calibration of a high-precision pin gage requires high-accuracy measurement.

Medical care

Hypodermic needle measurement

To reduce injection pain as much as possible, the outside diameter of hypodermic needle tips has become much thinner. Some needles have a tip diameter of just 0.2 mm, thus requiring high-accuracy measurement.

  Electric/electronic devices

Fiber optics measurement

The optical-transmission cylindrical "core" made of quartz glass is 0.01 to 0.05 mm in diameter. Since its thickness is similar to a strand of hair, high accuracy is required for its measurement.

 Manufacturing

Gap gage calibration

Gap gages are widely used for easy measurement of small gaps in assemblies.
Periodic gage calibration is indispensable for accuracy control to detect undue wear.

  Automobile and machine tools

Gear tooth measurement

As gears decrease in size and weight, the MDH allows for convenient high accuracy evaluation.
MDH simply enables accuracy evaluation with it on hand for the customer demand of high accuracy.

Medical care

Implant measurement

An abutment is used for dental implants. Abutments have various lengths, angles, and materials. Each abutment needs to be made and measured very accurately.

Medical care

Catheter measurement

High-accuracy measurement is needed when manufacturing the fine tubing widely used in the medical field, such as a catheter that plays a crucial part in dilating a blood vessel.

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 through hands has been reduced during measurement with this micrometer by fitting the supplied heat shield. The graph below shows that the heat shield almost eliminates hermally induced error by minimizing thermal expansion of the frame.

ABS (absolute) rotary encoder with a resolution of 0.1 μm 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 has also improved its reliability. Additionally, since the spindlethread 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.

Reliable operation

The sound of the ratchet provides a reliable operation and repeatable measurements.

Absolute encoder

The ABS (absolute) rotary encoder eliminates the need for origin point setting at every power-on, allowing immediate starting of measurement.
This encoder achieves high reliability without causing an overspeed error.

 Wear-resistant carbide tip

The ø3.2 mm carbide tip on the measuring face is highly resistant to wear, allowing accurate measurement for an extended period of time.

Zero-setting function

This function allows the displayed to be zero set at any position, thus facilitating comparative measurement. Also the absolute value from the origin can be restored.

 Versatile functionality enhances productivity and ease of use

This micrometer is equipped with many useful and time-saving functions such as resolution switching (0.0001 mm/0.0005 mm), function lock, and presetting.

Built-in "Hold" function

This function can hold (freeze) the displayed value. Enables the micrometer to be removed from a workpiece when the readout is not easily viewable so that the measurement value can be read at your convenience.
