Mahr Micromar 40 EWR Digital Micrometer 25-50 mm IP65

The Mahr Micromar 40 EWR Digital Micrometer is a high-precision measuring instrument engineered for professionals who require exact dimensions within the 25 to 50 mm range. Built with a robust frame and advanced electronic components, this micrometer ensures consistent accuracy in demanding industrial and workshop environments. Its IP65 protection rating provides a reliable shield against dust ingress and water jets, allowing for dependable operation even in challenging conditions where coolant or debris may be present.

Advantages

This digital micrometer stands out due to its exceptional build quality and user-friendly interface. The high-contrast digital display allows for quick and error-free reading of measurements, significantly reducing the time spent on quality control tasks. The integration of the Reference System ensures that the zero position is maintained once set, eliminating the need for constant recalibration. Furthermore, the lapped carbide-tipped measuring faces provide long-term wear resistance, maintaining precision over extended periods of heavy use.

Suitable for

• Precision engineering and manufacturing quality control
• Measurement of external dimensions for mechanical components
• Workshop environments with exposure to dust or moisture
• Routine inspection of turned or milled parts

When it may not be suitable

This tool is not intended for measuring objects outside the 25 to 50 mm range. It is also not suitable for use in environments where it might be fully submerged in liquids or exposed to extreme chemical solvents that could damage the electronic housing.

Key specifications

• Measuring range: 25-50 mm
• Protection class: IP65 (dust-tight and water-resistant)
• Display: High-contrast digital LCD
• Measuring faces: Carbide-tipped, precision lapped
• Reference system for permanent zero setting

How to use

To begin, ensure the measuring faces are clean and free of debris. Close the micrometer gently until the faces touch to verify the zero position. If necessary, use the reference function to set the zero point. Place the workpiece between the spindle and the anvil, then rotate the friction thimble until it clicks to ensure consistent measuring pressure. Read the value directly from the digital display. Always store the device in its protective case when not in use to prevent damage to the measuring surfaces.

What to consider before purchase

• Verify that the 25-50 mm range covers your specific workpiece requirements
• Ensure the IP65 rating meets the environmental demands of your workspace
• Consider the need for periodic calibration to maintain ISO standards

Usage recommendations

Always clean the measuring faces with a lint-free cloth before and after each use. Avoid applying excessive force with the thimble to prevent measurement errors and premature wear of the spindle mechanism.
