The Facom 25-50mm Precision Micrometer is a professional measuring instrument designed for accurate external dimensional measurement in engineering, automotive, machining, manufacturing and maintenance applications.

Offering a measuring range of 25mm to 50mm with an accuracy of 0.01mm (1/100th mm), this precision micrometer provides controlled and repeatable measurements where conventional rulers or vernier-style measuring tools may not provide the required level of precision.

The micrometer incorporates a Ø6.5mm carbide plunger tip, a finely graduated 50-division drum and a ratchet drum with torque limiter to help maintain consistent measuring force.

Isothermal pads help reduce the transfer of heat from the user's hand to the measuring instrument during use.

The micrometer is supplied with the appropriate calibration accessories, a plastic protective storage case and compliance certificate.

25-50mm Measuring Range

This Facom micrometer is designed to measure external dimensions between:

25mm and 50mm

This makes it suitable for accurately checking components such as shafts, pins, machined parts and other components that fall within the specified measuring range.

For accurate results, the measuring surfaces and component should be clean and free from dirt, swarf, oil contamination or other debris that could affect the reading.

0.01mm / 1/100th mm Accuracy

The micrometer provides an accuracy specification of:

0.01mm / 1/100th of a millimetre

This level of precision makes the tool suitable for professional mechanical and engineering applications where small dimensional variations need to be measured accurately.

50-Division Graduated Drum

The micrometer incorporates a Ø18mm drum with 50 divisions.

One complete revolution of the drum represents:

0.5mm

The graduated mechanism allows precise dimensional readings to be taken across the instrument's 25-50mm measuring range.

Carbide Plunger Tip

The micrometer features a Ø6.5mm carbide plunger tip.

Carbide provides a hard and wear-resistant measuring surface, making it particularly suitable for precision measuring instruments intended for regular professional workshop and engineering use.

Ratchet Drum with Torque Limiter

A ratchet drum with torque limiter helps control the measuring force applied to the component.

This is important when using a precision micrometer because excessive or inconsistent pressure can influence the measurement.

The controlled ratchet mechanism helps the user apply a more consistent measuring force when taking repeated measurements.

Controlled Measuring Force

The specified force applied to the measured component is strictly between:

5 and 10N

This controlled force helps provide repeatable measurements while reducing the influence of excessive manual pressure on the reading.

Isothermal Pads

The micrometer incorporates isothermal pads to help reduce heat transfer from the user's hands to the measuring instrument.

Temperature can influence precision dimensional measurements, particularly when working to small tolerances.

The pads provide suitable handling points and help reduce direct thermal influence during normal use.

Calibration Accessories Included

The micrometer is supplied with the appropriate calibration accessories, including:

  • Pin and hook calibration wrench
  • Calibration shim / setting standard for the 25-50mm model

These accessories allow the micrometer to be checked and adjusted as required to help maintain measurement accuracy.

Professional Measuring Applications

The Facom 25-50mm micrometer is suitable for precision measurement applications including:

  • Mechanical engineering
  • Automotive engineering
  • Engine component measurement
  • Shaft measurement
  • Machined component inspection
  • Manufacturing
  • Machine shops
  • Workshop inspection
  • Maintenance engineering
  • Quality control
  • Component checking
  • Industrial maintenance
  • Aerospace maintenance applications

Plastic Storage Case

The micrometer is supplied in a protective plastic storage case.

Precision measuring equipment should be stored carefully when not in use to protect the measuring surfaces and adjustment mechanism against accidental damage, dirt and workshop contamination.

The dedicated case also keeps the micrometer and its associated accessories together for convenient storage and transportation.

Compliance Certificate Included

The micrometer is supplied with a compliance certificate, providing supporting documentation with the instrument.

The compliance certificate should not be confused with an independently accredited calibration certificate unless specifically stated as such.

Frequently Asked Questions

What measuring range does the Facom precision micrometer cover?
This professional outside micrometer has a measuring range of 25mm to 50mm. It is suitable for accurately checking external dimensions of components such as shafts, pins, machined parts, engine components and engineering components that fall within this range.
How accurate is the Facom 25-50mm micrometer?
The micrometer has a stated accuracy of 0.01mm, or 1/100th of a millimetre. This makes it suitable for professional engineering, automotive, machining, manufacturing, inspection and maintenance applications where precise dimensional measurement is required.
What is the purpose of the ratchet drum and torque limiter?
The ratchet drum with torque limiter helps apply a consistent measuring force to the component rather than relying entirely on pressure applied by the user. With a specified measuring force of 5-10N, this helps improve repeatability and reduces the possibility of excessive pressure influencing the measurement.
What are the isothermal pads used for?
The isothermal pads provide designated handling areas that help reduce heat transfer from the user's hand to the micrometer. This is useful during precision measurement because temperature changes in the instrument or component can influence dimensional readings when working to small tolerances.
Does the micrometer come with a calibration certificate and storage case?
The micrometer is supplied in a protective plastic storage case together with a compliance certificate. The supplied compliance certificate should not be confused with an independently accredited calibration certificate unless specifically stated. Periodic calibration or verification may still be required depending on your workshop, inspection or quality-control procedures.
