Hello forum

I am looking for information about an old Etalon 6" dial caliper gage pictured here:

I'm a new user so I can't post url. it is ebay item # 310044387914

I've already purchased the instrument and spoken with the seller, and it appears that he has more of these older, higher quality instruments. I might purchase more of them if I knew more about them.

It appears that it is authentic new packaging from Etalon, and that an instrument with an old logo was packaged in a case with a new logo near the time their trademark was changed.

Does anyone know when Etalon changed their logo from the old style badge to the new monochromatic horse?

Hello apestate,

Welcome to The Cove Forums! :bigwave: :bigwave:

Etalon is a (super high quality) brand from TESA in Switzerland.

Look at this catalog. You can send also an email to TESA to find out.

Re: Etalon dial caliper gage

Thanks for your reply Stijloor

I used to have one of these instruments that I purchased new from J&L. It had the modern Etalon big black horse logo on it.

The shop was undergoing some quality improvements and we sought to replace many cheap calipers that were in poor condition, so we bought and tried at least a dozen different brand calipers.

We settled with the Mitutoyo 505's made in Brazil for around $70 a piece. At first the accuracy of these Brazilian 505's was sub-par, but complete disassembly and careful reassembly yielded a highly accurate instrument. The new Brazilian 505's are very accurate. Mitutoyo's are easy to re-assemble if you know how.

However, we took apart the Etalon 6" dial caliper for comparison and had a wicked time of re-assembling the instrument. Actually, I took it apart and ended up with a basket case. I challenged my co-worker to re-assemble it and gifted it to him as a reward. He is an order of magnitude more meticulous and tireless than I.

The Etalon had a press fit assembly and much larger gears. It is fully rubied and of heavier construction. Very difficult to work on.

Of course this is getting a little esoteric, since a Mitutoyo 505 or Brown & Sharpe dial caliper is already as accurate as a caliper should ever need to be.

However, as an illustration, imagine you had to sort a bunch of class ZZ gage pins that someone left out of the index. These gage pins are sized by .001". A high quality dial caliper like the Brown & Sharpe or Mitutoyo could possibly give you an error up to .001", especially at different angles of rotation on the dial. I would see this commonly while using my calibration procedures.

The Etalon 6" dial caliper did not exhibit this inaccuracy. In fact, the Etalon would often indicate whether a gage pin was + or - tolerance class! This is superior to brand new Brown & Sharpe dial calipers, although I have seen brand new and custom-refitted Mitutoyo 505's that would allow you to sort gage pins by .001" without easily making an error.

Maybe I'll get my post count up to 5 so I can post my calibration procedure and repair procedures for discussion!
