MarTest Test Indicator
Fühlhebelmessgerät - Comparateur à levier
Quality test indicators made in Germany — Guaranteed genuine

We are pleased to add these new Mahr Federal introductions to our catalog, for the connoisseur of German made measuring instruments. MarTest indicators are new model replacements for the popular Puppitast indicator made by Mahr of Germany. Originally patterned after the Swiss BesTest indicators, the new models bear a strong similarity in construction to the Japanese Mitutoyo models.

These indicators are beautiful, sturdy and very responsive.

Test indicators are used for comparative measurements. They can be used in any type of measuring stand. Since the contact point swivels and can be used in the up or down direction, the MarTest indicator is suitable for various measuring and inspection tasks. For example:

  • Testing concentricity and run-out of shafts and bores.
  • Testing of parallelism and alignment of sufaces in engineering and tool making.

Q: I have a question about using a deadblow to tap the vise on my mill while I am indicating it with my Mahr 801SG. I used to indicate the vise by running it in the x axis will taping it with a deadblow while the indicator was on it to dial it in.  I no longer do this because I figured the shock is something that may not be good for the DTI. Is this correct or am I being overly cautious?

  • You are not being overly cautious. Although we can’t be certain it will cause any particular damage to the indicator, the vibrations, blows, shocks, bumps, etc. of any kind from any source could be detrimental. You have made the right decision.
