Brown & Sharpe Micro-Master

extended measuring range digital micrometer

The new, ergonomic design allows for easy one-handed operation (but this can be difficult if the hands are small).

Brown & Sharpe Micro-Master digital micrometers conveniently measures beyond 1" (up to 1.2"). This basic model has just one button, so it's a cinch to use by anyone. The models shown on this page do not have SPC output.

High-quality Swiss made with all the features that make Swiss micrometers famous. All feature a waterproof rating of IP40 or IP54. In the table below, the Tesa number is used for international marketing, while the B&S model number is specifically assigned to the Brown & Sharpe branded version sold in the USA. There is no difference other than the slightly lower price of the B&S models.

What can go wrong?

Your digital display may show an error message such as Err1, Err2, or Err3. If this happens, remove the battery and wait one minute before replacing it. This might solve the problem. If not, then you'll want to have the micrometer serviced. Note: obtaining repair service for this series of micrometers may be problematic. Spare parts are often hard to come by and this should be kept in mind when buying these gages.

  • They come with a 1-year warranty, so check to see if it applies before sending it anywhere.
