What Is The Best Digital Micrometer?

Micrometers are not a new thing, as they have been in the scene for a long time. For measuring the smallest of the measurements, micrometers are used. Mechanical micrometers helped read the smallest of measurements, but the reading part needed to be done manually, which is by reading the scale. Some use to find the scale reading quite hassle, as there is always a certain chance of error in it. But with the best digital micrometer, that particular chance is reduced significantly.

What is a digital micrometer?

Digital micrometers are an advanced version of mechanical micrometers. They are practically the same as the latter but have an LCD screen, which shows the measurements. This particular innovation quite new and recent, as it is brought in the game to increase the accuracy and also usability of the micrometers. The measurements that a micrometer, in general, can measure ranges from 0.0005 inches-0.001 mm (metric or imperial units).

In digital micrometers, there is also a button that can be pressed to change the unit of measurements (mm/inch). Also, the micrometer can be zeroed easily with a single press of a button. This makes it quite easier when one needs to take continuous measurements or need to take incremental measurements.

In a digital micrometer, one can get instant results and measurements which can be jotted down. Also, certain models allow connecting to a computer while taking the readings. This way, the measurements will be stored on the computer, and one will not have to write it down.

Types of digital micrometers

There are several types of micrometers that one can find like:

  • Disc micrometers
  • Blade micrometers
  • Spline micrometers
  • Spherical face micrometers
  • Point micrometers
  • Screw thread micrometers
  • Tubing micrometers
  • Uni mike micrometers
  • Step mikes micrometers

How to pick a digital micrometer?

As mentioned above, there are several micrometers in the market to choose from, thus making it quite difficult which one to choose for precise readings. There are a few things that can be considered before choosing the best digital micrometer like:

Range of measurement

Every micrometer has its measurement range, and depending on the type of work on should choose the relevant one. The range of micrometers is generally of 1 inch. Measurements of the micrometers are precise, and thus one should forts have an idea which ranges to use to get correct readings.

Anvil

Anvil is the part that touches the surfaces of the object that needs to be measured. There can be any type of anvil to choose from. Make sure that the anvil can fit into the space that needs to be measured and that it does not compress the surface. The diameters should be precise to avoid unnecessary compressing of the material to be measured to avoid discrepancies in the measurement.

Accuracy and precision and resolution

When it comes to measuring in the world of metrology, accuracy, resolution, and precision play a very big role. The accuracy of the tools is depicted by the uniformity of the actual value with the measured value. Smaller the measuring uncertainty, the higher will be the accuracy of the micrometer. This means the micrometer must have a smaller error range for better performance.

Resolution is another component that decides how the smallest is a measurement a micrometer can measure. Smaller the result of a micrometer, better is its measurement capability. The standard resolution of a micrometer to find is 0.01 mm.

Precision is another component that tells if the micrometer is worth a buy or not. Precision can be gauged by measuring the same things for at least 10 to 15 times. If the measurements come around the same, then it is precise and consistent.

Dust and water resistance

A good micrometer should have an IP (ingress protection) rating, which depicts how much the device is resistant from water and dust ingress. A digital micrometer must have an IP rating, especially if it will be used in stressful and harsh conditions. IP rating will make sure that the readings are consistent, and measurements are not harmed due to water exposure or entry of dust in the micrometer.

Settings

Check the buttons and settings before buying a micrometer, as it will help in understanding the accuracy and working in a better way. There should be a proper setting to change the unit of the measurements. There should be a zero button to make the micrometer come back to its zero position. There should be an original setting to calibrate the micrometer when the micrometer is not in work. Among setting include hold button for keeping the measurement stat, on/off, and data to transfer the measurement to a computer.

Price of the micrometer

Lastly, one should focus on micrometers price. It should not be too up, and it should not be too low as well. If one wants better features, good accuracy, IP rating, and also data transference feature, then they should choose to buy a good brand giving an optimal price.

Benefits of digital micrometer

Many factors make a digital micrometer the best digital micrometer in the market are:

IP rating

These micrometers have an IP rating of IP67, which certifies that the micrometer is moisture and dustproof. Such a rating is important when one is going to use it for workshop related activities.

Resolution

If the micrometer has a resolution of at least 0.001 mm, then it is a much better choice over a resolution of 0.01 mm. Thus one should go for a digital micrometer of 0.001 mm resolution or else buy a caliper.

Certified

Every certified digital micrometer will state its traceability to NIST. Such a certification gives assurance that the tool will give accurate observations. At times such certification is not particularly necessary but is important in case of any formal use.

Absolute zero

Another benefit that is helpful during the measurement is the micrometer’s capability to remember zero points even if the micrometer is turned off. Such a thing in the system supports accuracy at the time of making measurements.

Accuracy

A digital micrometer that is certified will be able to provide accurate measurements with very few chances of uncertainty.

Final words

Mircomtwers are a big part of the manufacturing industry, but to cope with the increasing demand for accuracy and time compactibility, digital micrometers are proven to be more useful. One can choose their micrometers based on what their purpose is, what the object is, and how precise they want the measurements to be.
