- Type: This depends on the subject of the measurement. Blade micrometers are for groove diameters. Point micrometers are for measuring the thickness of drills. Meanwhile, for measuring the thickness of paper or metal, you will need a deep-throat micrometer.
Here are some questions you might have about digital micrometers and our brief answers.
What is a Digital Micrometer?
At the most basic, a digital micrometer is a precise measuring tool. It measures diameter, depth, distance, thickness, and groove. It is more accurate compared to a mechanical micrometer. One of its benefits is precision as it measures up to .0005 inch. There is an electronic display that makes it easier to see the measurements.
What is the Least Count of Digital Micrometer?
The least count refers to the minimum measurement a digital micrometer can take. It is .001mm. This is as against a mechanical micrometer, which measures only a minimum of .01.
How Does a Digital Micrometer Work?
Start by cleaning and drying the surface of the object you wish to measure. Do the same in your digital micrometer. Close the micrometer and align the zero value with the thimble. Turn it on and make sure the screen shows 0. Open the jaws by rotating the hatchet. Place the item you want to measure in between the anvils. Rotate the ratchet until the spindle gets in contact with the surface of the object. Look at the screen to see the readings.
The digital micrometer will generate readings electronically, available in both metric and imperial units. In most models, you can instantly switch the values from inches to millimeters or vice versa. Often, there is also a zero button that allows you to instantly reset the reading. There are also models with data output capability, which allows users to connect it to a computer.
Whenever you need to take measurements of small objects, the best digital micrometer is a handy tool. It is a precise measurement gear that generates results in an instant, unlike mechanical ones that can be prone to inaccuracies.
