Product description (as provided by the manufacturer)

Mahr Federal MarCal 4103011 16 ER Digital Caliper, has a 0 to 6" (0 to 150mm) measuring range with 0.0005" (0.01mm) resolution and round depth rod for precision results. MarCal Calipers with the REFERENCE symbol are equipped with the innovative Reference-System. The zero position just has to be set once: after setting the zero position, the zero remains stored for all further measurements. Therefore, once the caliper is switched ON or the slide is moved the caliper is immediately ready for measurement. The need to reset to zero with a conventional caliper once the caliper is switched on has now become obsolete.

Its Large "New Look" digital readout LCD shows inch or metric units for versatility, and allows either absolute or incremental measurement readings. MarCal 16 ER delivers precise and secure results even in the most difficult workshop conditions. The finished plastic components have an excellent outstanding chemical resistance. Digital calipers are measuring instruments commonly used for inspection in manufacturing to provide the precise measurements of an object. The electronic caliper measures inside, outside, depth, and step values for versatility and includes a protective case and battery.

More About Calipers

There is no question that Amazon can offer you the best prices on almost every kind of precision measuring tool. They also offer easy no-questions-asked returns and often free shipping. The small distributor simply cannot compete. That's why we include this link so you can go directly to Amazon and see what they're offering.

Two things to consider:

  • Amazon product photos sometimes don't match the product description. It's the description that you want to pay attention to.
  • There are imitation gages on the market (specifically Mitutoyo) and you can make sure you are getting the real item by looking for the words "sold by Amazon". If it is sold by a third party, you might want to call Mitutoyo to find out if they are legitimate distributors.
