Mercer Dial Indicator - small dial

Swiss Precision Dial Gauge with 40 mm Ø bezel
The best dial indicator available

The new generation of Mercer dial indicators are made in Switzerland. These are some of the best inch-reading as well as metric dial indicators available. Many of them are now in stock, and others can be had in about 3 weeks. We present here the most popular models, but please don't hesitate to contact us regarding any indicator with the Mercer name.

One caveat: the old-style Mercer indicators were made in England. Those are no longer available, but you can substitute the new models with confidence. They're a dramatic improvement over the old ones.

Mercer indicators have 8 mm diameter stems and use 2.5 mm contact point threads. The 8 mm stem can be changed to 3/8" using an optional adapter sleeve. They are identical to Compac indicators, using the same stainless steel racks which give these a long useful life. While Compac has discontinued most of its inch reading models, you can find the equivalent still available with the Mercer name.

It's important to note that these come with flat backs. If you need lug backs, you'll have to order them separately.

 

Mercer Ø 40 mm dial - Ø 8 mm stem

 

Model 183-1 on the left has a balanced dial. Model 184-1 on the right has a continuous dial. That's the only difference on these small (40 mm diameter) dial indicators made in Switzerland. Note the bezel locking clamp. The two black tolerance markers are adjustable to help you remember your tolerance limits. Unlike for the large models, these tolerance markers are adjustable but not removable. A bezel lock will keep the dial from turning on its own.

A factory certificate of calibration and declaration of conformity are included. If NIST traceable data is required, you will have to send the gage to an accredited laboratory. The indicators come in a cardboard storage box.


If you are not sure which dial type is correct for your application, please take a look at
