## Summary description

Digital micrometer Mahr 40EWRi-L with measuring range 0–25 mm, IP65 protection and integrated radio (wireless) data transmission. Designed for precise external dimensional measurement with digital readout and robust sealed housing for shop-floor use. Suitable for quality control, metrology and production environments requiring accurate, repeatable thickness and diameter checks.

## Long description

The Mahr 40EWRi-L digital micrometer is a precision measuring instrument for external dimensions with a 0–25 mm measuring range. It combines a digital display with a sealed housing rated to IP65 and integrated radio data transmission for wireless transfer of measurement values. The instrument is intended for shop-floor use where reproducible thickness and diameter checks are required, offering robust construction suitable for quality control, metrology and production environments.
Advantages
The micrometer provides accurate and repeatable readings through a digital encoder and clear numeric display. Its IP65-rated sealed housing protects internal components from dust and water jets, enabling reliable operation in industrial environments. Integrated wireless radio simplifies data capture and reduces manual entry errors by sending measured values directly to compatible receivers or data-collection systems. The compact 0–25 mm design supports close-tolerance external measurements while remaining easy to handle.
Suitable for
External diameter and thickness measurement of small parts
Quality control and dimensional inspection on the shop floor
Metrology tasks requiring traceable, repeatable readings
Production environments where wireless data logging is used
Key specifications
Measuring range: 0–25 mm
Protection class: IP65 (sealed against dust and water jets)
Display: digital readout for direct numeric values
Data transmission: integrated wireless radio for remote data transfer
Application: external dimensional measurement (micrometer-type)
How to use
Place the micrometer anvil and spindle around the part to be measured and close the spindle until it contacts the workpiece with steady, consistent force. Read the measurement directly from the digital display or transmit the value via the integrated radio to a compatible receiver or data-collection system. Follow standard metrology practice: ensure the instrument and workpiece are clean, allow temperature stabilization, and use a consistent measuring technique to achieve repeatable results.
Usage recommendations
Use the micrometer in controlled temperature conditions where possible, avoid exposing the device to strong impacts, and rinse off chips or coolant before measuring. Regularly check calibration against gauge blocks or standards and store the instrument in its protective case when not in use to preserve accuracy and the IP65 sealing.
