The Brown & Sharpe TESA Etalon dial caliper has an accuracy of 0.001", a 1.25" diameter rotating dial with a lock, is made of stainless steel, and measures in inches. The covered rack helps prevent measurement error by protecting the gear from foreign matter. Linear accuracy meets Deutsches Institut für Normung (DIN) 862 standards. These calipers are for use in measuring inside dimensions (ID), outside dimensions (OD), depth, and step.
The caliper measures 0.100" per revolution of the dial. The lock screw locks the dial and holds the sliding jaw in position. Adjustable zero set allows the user to set zero at a convenient distance. The depth rod is integrated into the rack of the caliper, unlike many calipers that offer a detachable depth rod, or none at all. The hardened stainless steel components, including the bar, measuring surfaces, rack, gears, and depth rod, offer corrosion resistance, increased accuracy, and long life. Spring anti-backlash control offers increased accuracy over standard gear configurations. Backlash is the amount of clearance between mated gear teeth in the caliper controls, which prevents the gear teeth from jamming. It is undesirable to have much backlash due to the lack of precision offered by the increased amount of play between gears. Certain gear designs can minimize or eliminate backlash; spring anti-backlash systems use a spring to add a compressive force, thereby minimizing backlash.
Calipers measure the distance between two opposing sides of an object. They make inside, outside, depth, or step measurements, according to their type. Calipers are commonly used in architecture, metalworking, mechanical engineering, and machining. The simplest calipers have two legs to mark the two points and require a ruler to take the measurement. More complex calipers use two sets of jaws instead of legs and have up to two graduated scales. Vernier, dial, and digital calipers give direct and accurate readings and are functionally identical, having a calibrated scale with a fixed jaw, and another jaw with a movable pointer that slides along the scale. The vernier caliper has a scale sliding parallel to the main scale for an additional, fractional reading to improve measurement precision. The dial caliper has a circular dial with a pointer on a toothed gear rack replacing the second vernier scale. As with the vernier, this second measurement is added to the reading from the main scale to obtain the result. The digital caliper takes a differential by zeroing the display at any point along the slide, with an LCD that displays a single value in English and/or metric units.
Brown & Sharpe manufactures precision measuring equipment and metrology hand tools. The company, founded in 1833, played a key role in setting industrial standards in the United States. Brown & Sharpe was acquired by Hexagon Metrology in 2001 and is headquartered in North Kingstown, RI.

I have been using a variety of calipers (mostly digital) for various hobbies: handloading ammo, custom gun work, electronic device designing, guitar customizing, machine repair, and the list goes on.
I've tried to avoid the dial because of the obvious "brain fart" moment you get when reading it for the first moment (sort of how we've become used to digital clocks compared to their analog equivalents), but I have still used dials and verniers. I've always liked the conversion of Inch, mm, and fraction on high quality digital calipers, but have preferred the dependability of dials and the fact that they are not dependent on power. Dials are also impervious to EMF fields which may cause the decoder of digital calipers to be thrown off (when next to some types of fluorescent lights, as an example).
I mention the above because I've gone through many calipers. Something was always off about one or another. Not aligned right, wouldn't zero, loose mechanisms - just something would always keep them from being excellent.
This specific caliper is designed and made in Switzerland by TESA, branded Etalon, and I believe imported by Browne & Sharpe (who also makes great tools themselves). I purchased the black face with orange hand because the orange contrasts against the black face easier for reading than the alternate model with gray face and black hand.
This model includes a thumb wheel, covered gear bar, a locking alignment screw, and a locking mechanism screw. The caliper obviously takes four measurements: outside, inside, depth, and step. Don't expect instructions with it...
The quality of the housing is perfect, and reminds me closely of my custom shop Sig Sauer pistol (Swiss designed, and German made).Read more ›
I get more accurate and reproducible (consistent) measurements with this dial caliper than with the high-end digital one I had been using. I only wish I had bought it sooner.
It is a pleasure to give this Brown & Sharpe dial caliper my highest recommendation.

I suppose it works great. I don't use it very often because the numbers are so small I have a hard time reading them. I opt for a $25 caliper from Frankfort Arsenal.Published 4 months ago by bearridge
Nice calipers real smooth tighter than starret and smoother doesn't say brown and sharp on them case is junkPublished 15 months ago by Rob
