Mahr Micromar 40 EWR-L 1″-2″/25mm-50mm High Resolution Digital Micrometer – 4157021

Mahr Micromar 40 EWR-L 1"-2"/25mm-50mm High Resolution Digital Micrometer - 4157021

The Mahr Micromar 40 EWR-L 1"-2"/25mm-50mm High Resolution Digital Micrometer is a precision measuring instrument designed for high accuracy and sensitive applications. Engineered with a non-rotating spindle, this micrometer prevents scratching and marking on finely machined surfaces, making it ideal for measuring delicate materials such as thin metal foils without twisting or bending them.

With an IP65 protection rating, this digital micrometer is resistant to dust, water, and coolant, making it suitable for use in demanding environments. The high-contrast digital display ensures easy readability, while the sliding spindle and QUICK DRIVE mechanism provide fast and precise adjustments.

The Micromar 40 EWR-L also features an integrated ratchet in the thimble, which guarantees consistent measuring force, reducing user variability and improving repeatability. Its MarConnect data interface (USB, Digimatic, and bidirectional) allows for seamless data transfer, making it a valuable tool for quality control and documentation.

This high-resolution digital micrometer meets ISO 3611 standards for precision measurement and includes thread flank measurement capability using thread wires, with holders that remain engaged during operation. The lacquered steel frame with heat insulation further enhances stability, minimizing the effects of temperature fluctuations on measurements.
