Features to Look for

Virtually all consumer grade digital calipers use .0005” (.01mm) resolution, and will claim a tolerance of about +/-.001”. The truth about tolerance is a bit different, however. In reality, only the very best digital caliper models can measure down to .001 reliably.

That doesn’t mean that digital calipers costing less $100 are junk, though! Even the cheapest digital calipers are usually pretty accurate, with tolerances of .005” along a 6” caliper. For the average home user, or for anyone who doesn’t need absolute accuracy down to the thousandth of an inch, just about any digital caliper is accurate enough.

Accuracy isn’t the only feature to consider when choosing the best digital caliper. These features are also important to look out for:

  • Battery. The kind of battery a digital caliper comes with is often an indicator of quality throughout the unit. Silver oxide (SR) and lithium (CR) batteries last twice as long, provide stable voltage throughout their lives, and resist corrosion better than alkaline (LR) batteries. The good news is that even if your digital caliper comes with an LR coin cell battery, you can replace it with the silver or lithium equivalent.
  • Construction. Like any tool, there’s a level of construction quality to expect from the best digital caliper. Look for a digital screen that’s firmly attached to the rail without any wiggle. Steel edges should be smooth, and there should be no space between the teeth of either the exterior or interior jaws when the calipers are closed.
  • USB Outputs. Taking a lot of measurements at one time? High quality digital calipers with USB outputs can be plugged into a computer for easy recording. This is an indispensable feature in professional settings.
  • Protection. Many of the best digital caliper models are resistant to environmental contaminates like dust, oil, and water. Mechanics should look for coolant resistant calipers, and always be sure your calipers are made of rust free materials like stainless steel.

Like the more expensive Mitutoyo, this digital caliper is dust and oil resistant as well as waterproof. Solidly built, the iGaging doesn’t rattle like lesser digital calipers and comes out of its protective casing straight as an arrow.
