Types of Micrometer Bookmarked

In the previous article, we have talked about the differences between micrometer and caliper. As we know, a micrometer is not as versatile as a caliper. Micrometer only comes with a specific function in its unit. While calipers can cover several measurements in a single unit of the caliper.

As our observation on the web, these are our findings and also we include the pictures of the several models of micrometer currently available.

Based on The Dimension It Measures

You will require three units of mic to measure outside, inside and depth. 

1. Outside Micrometer

Outside micrometer is the most used mic. It clamps the object from outside side. It measures thickness, outside diameter, width, and length. But, its range is short. The most common is 1".

2. Inner Micrometer

As the name tells, it measures inner dimension such as inner diameter.

3. Depth Micrometer

A single unit of caliper can be used to measure depth. A micrometer doesn't. There is a model called depth micrometer. The look can be seen on the following picture.

Based on Its Scale Model

1. Vernier Micrometer

Vernier micrometers manifest and employ vernier scale to magnify its measurement. Unlike other micrometers, this kind of micrometer has better resolution because there are three scales printed. They are the main scale on the barrel, the scale on the thimble, and the horizontal scale on the thimble which is called the vernier scale. The Vernier scale is also used in the vernier scale. 

2. Dial Scale Micrometer

It employs the dial scale like the dial caliper. The needle rotates to show reading. However, it's rare for us to see this model on the market. Perhaps, you have one in your shop.

3. Mechanical Counter Micrometer

Like a tally counter, this one has mechanical counter as the reading display. It's unique. But, this one is not popular.

The real look can be seen in this Youtube video.

4. Digital Micrometer

Digital micrometer serves you with incredible speed for measurement. You are no longer to reading the read the two scales. You can instantly get the reading through the LCD screen. Today's digital micrometer is also be able to allow you transfer the data to your smartphone or computer. Herewith, you can also make a rapid repetitive measurement because the reading is directly stored in your spreadsheet.

If you have many objects to measure, a digital micrometer with data transfer feature can be a nice investment.

The above digital micrometer applies touchscreen. As you can see it allows Bluetooth connection and wifi for data transfer.

Another advantage of a digital micrometer is its analog reading availability. Though not digital micrometer allows you to take the reading manually. When you are about to run out of battery, you are still able to use it.

Based on Its Anvil Shape

1. Flat Anvil Micrometer

It's easy to identify the anvil surface of the above picture. As you can see, it's flat.

2. Ball Anvil Micrometer

To quantify the thickness wall tube, a ball micrometer is recommended. It's less error compared to the usual anvil (Flat). Ball micrometer is applied in reloading. 

3. Thread Micrometer

6. Paper Micrometer

Designed exclusively to measure paper thickness.

7. Deep Throat Micrometer

8. Pitch Micrometer

9. Three Point Bore Micrometer

10. Three Flute V-Anvil Micrometer

That's all guys. Never ever again you get confused the types of micrometer. Another type is based on the reading. There are metric and imperial mic. Metric uses mm while imperial uses inch. This is just about how familiar you are. If you live in the USA, then you have to prefer the inch reading.
