Mahr launches new family of Micromar 40EWRi-L digital micrometers

Tuesday September 04, 2018
September 4, 2018 - Mahr, a provider of dimensional metrology solutions, has launched a new family of Micromar 40EWRi-L digital micrometers with high-speed measuring spindle positioning.

The spindle makes a five-millimetre movement with one revolution of the friction drive sleeve and can be positioned 10 times faster than a standard micrometer. By carefully contacting the part with the non-rotating sliding spindle, scratches (e.g. from grinding dust residues on sensitive and finely machined part surfaces) are avoided. In addition, the non-rotating system provides a solution for measuring film thickness without twisting and damaging delicate, thin materials during measurement. 

The new micrometer is available in eight standard ranges of 0 through 4” in 1" increments (0 through 100m in 25mm increments). Measurement data and the unique serial number of the instrument is transferred to an i-Stick on a computer via the proven “integrated wireless” system – without any interfering data cables. 

Users can take a measurement and transmit measuring data directly into MS Excel or via a keyboard code into any Windows program without the need for external transmitters or cumbersome cables. It's also possible to apply the wireless data collection capabilities to existing SPC applications. The micrometer confirms via a message on the display whether the data was transferred correctly. 

Micromar 40EWRi is the first digital micrometer with 10-mm digits on a high-contrast digital display, which also logs a tolerance display with warning limits.
