A 75 100mm micrometer mitutoyo is an essential tool used in industries for precision measurement. These micron measuring tools come in various types to suit specific needs and applications.
Outside Micrometer
The most popular outside micrometer is the measuring instrument that measures the individual thickness of the outside section of a specimen, perhaps a wire or a sheet of metal. It has two fixed surfaces and a moving surface in the form of a thimble for taking the measurement. An outside micrometer is one of the highly used tools in engineering, mechanical work, and quality control.
Inside Micrometer
An internal micrometer measures the inside diameter of holes, tubes, and spaces. It uses extension rods and measuring heads that go through the narrow space. Inside micrometers are widely used in assessing the hollow spaces of engineering components and ensuring accurate roundness.
Depth Micrometer
A depth micrometer is slightly different from the first two. While the outside and inside micrometers measure thickness and diameter, depth micrometers measure the depth of grooves, holes, and cavities in a given substrate. Depth micrometer tools have rods or probes that reach the bottom of the measured irregular surface. These micrometers are typically used in machining and measuring.
Screw Micrometer
A screw micrometer is a highly precise measurement instrument, especially in measurement units that require a higher precision level. It uses a screw mechanism to enable incredibly high precision micrometer measurements. Screw micrometers measure thin sheets of metals, small-turn bolt nuts engineering parts, or even measure the precision of dielectric substrates for electronics.
Digital Micrometer
Digital Micrometers Outside, Inside & Depth Micrometers have replaced traditional analog screw micrometers in terms of display measurement. They present measurements on an LCD to enhance entry. Digital micrometers allow users to switch between measurement systems and feature automatic readings, which minimizes human error. They are highly valued for their efficiency in many industries, such as aerospace and precision engineering.

Quality Control
Micrometers are precious in quality assurance and control. Testers use them to measure finished products and determine if they meet specified standards and client expectations. The outside and inside micrometers check product dimensions, while the depth micrometer assesses surface features. This procedure reduces defects, averts rework and recalls, and ensures satisfaction.
Metalworking
In the metalworking industry, external and internal micrometer tools measure metal sheets, bars, and coils to assess thickness, width, and diameter. These measurements are used to cut, bend, and assemble metal parts for machines, cars, constructions, and many more. Depth micrometers measure grooves and slots in machining operations.
Tool and Die Making
Micrometers are necessary equipment in tool and die making. For example, an outside micrometer measures dies and molds, while an internal micrometer measures inside branches and cavities. These precise measurements guarantee the proper functioning of tools used for the production of various items.
Electronics Industry
Micrometers are also used in measuring insulators and components such as substrates and semiconductor materials, which need extremely accurate measurements. The digital micrometer’s outside, inside, and depth micrometers for measuring electronic items are suitable for this field.
Measurement Range
A 75 100mm micrometer measures 75mm to 100mm. This range makes it ideal for precision surface measurements in various fields.
Resolution
Mitutoyo 75-100mm micrometers measure thickness with 0.01mm resolution. Some digital models have 0.001mm resolution for more refined measurements.
Accuracy
Micrometers have an accuracy margin of ±0.02mm within the measurement range. Digital micrometers have improved accuracy, often ±0.005mm.
Measurement Interface
Conventional micrometers have thimble and sleeve divisions for reading. Digital micrometers offer LCD for easy readings and switching between measurement units.
Operating Temperature
Mostly, Mitutoyo micrometers are operable within 0 to 40°C. However, performance is exponentially increased when the temperature is around 20-25°C.
Power Supply
Some digital micrometers work with batteries or solar energy. Conventional micrometers do not employ any power but require oil lubrication for protection.
Material
Micrometers are largely fabricated using steel or hardened alloys for higher wear-resistance. The precision measuring instrument's external casing is often rubberized or made of plastic for better grip and shock-resistance.
Water and Dust Resistance
Not all, but many of the digital ones are waterproof and dustproof for the application in unclean or wet work environments. Mitutoyo micrometers of this kind conform to IP65 protection standards.
Thimble and Anvil Alignment
For outside and inside micrometers, users should ensure that the thimble and anvil are aligned properly and that the measuring faces are in contact. For depth micrometers, the depth rod should be retracted to avoid damage to the probe.
Locking Mechanism
New micrometers have a locking mechanism to avoid mistakes in measurements. Users should lock the thimble to keep the faces in contact tightly.
Calibration
Micrometers need calibration prior to use, especially after they have been dropped or used for a long time. To calibrate, users can use gauge blocks or comparison standards. The thimble should be rotated until it coincides with the gauge block measurement, and then the thimble lock should be locked.
Zeroing the Instrument
To Zero a digital micrometer, users have to close its measuring faces by turning the thimble until it reads '0.' For analog ones, the micrometer should be closed, and any readings should be adjusted to '0' using the micrometer's fuzzy cap or micrometer screw.
Taking Measurements
The workpiece to be measured should be placed between the measuring faces. The thimble should be slowly turned until it just contacts the workpiece on both sides. For internal measurements, the micrometer ends should be inserted into the diameter of the hole, tube, or spaces.
Locking the Thimble
Measurements will be taken by locking the thimble. It is worth noting that for depth micrometers, the depth rod should be inserted into the measured hole, and then the micrometer's thimble should be turned until the probe touches the bottom of the hole. For extra depth micrometers, the micrometer should be closed, and then the depth micrometer's thimble lock should be locked.
Reading the Measurement
Measurements are obtained in digital micrometers by looking at the digital screen. Analog micrometers require more work because users have to get the measurement by looking at the thimble and sleeve readings and doing some calculations.
Proper Cleaning
Cleaning the micrometer should be done after every use, especially when it is used in a dusty or humid environment. The measuring faces and frame should be cleaned using a soft, lint-free cloth. A compressed air can also be used to remove particles from internal components. Cleaning prevents wear and tear and thus enhances performance.
Lubrication
Lubrication should be performed on the moving parts of the micrometer to minimize friction. Oil should be deposited sparingly on the screw and thimble area. Excess oil should not be left because if there was excess oil, dust and dirt would be attracted to it, which may cause some hindrance to the movement. Lubrication needs to be done every few months, depending on the use frequency.
Calibration Check
Calibration should be performed periodically, ideally every few months, to ensure measurement accuracy. Gauge blocks or calibration standards should be used for the calibration check. Comparison with standard measurements will identify the need for recalibration. Many digital micrometers have automatic calibration features that must be checked.
Environmental Protection
Micrometers should be stored in dry, cool, and dust-free environments to prevent internal and external part damage. It should be protected from direct sunlight, high humidity, and extreme temperatures, as these factors affect the materials and components. The micrometer should be kept in its protective case when not in use, and waterproof digital models should be covered.
Drop and Shock Protection
Micrometers should be used and handled carefully to avoid being dropped or subjected to hard impact. It can cause serious internal misalignment or damage, which will affect measurements. In case of dropping or banging, a thorough check for calibration and accuracy and possible reparation or professional servicing is needed.
Regular Inspection
Wear and tear should be checked regularly for micrometers, focusing mainly on the measuring faces, thimble, and screw. For micrometers with additional attachments, like depth rods, they should be examined for bending or chipping too. If worn or damaged components are detected, they should be replaced or repaired, as they affect accuracy and precision.
