Buying Guide: Things To Consider When Buying A Micrometer
When looking to buy the best micrometer for you and the things you need to get done, there are a few things you should consider. Doing your due diligence is an important step for you to go in the right direction.
One of the first places to start is with the width ranges of sizes. Determine what material you need to measure and how often you will use a micrometer to measure this quantifiable resource. If you are looking to measure smaller items, 0-1” may work for you. However, if you have larger material to measure, you may need anywhere between 1-4” micrometers.
Knowing Tolerance Levels
If accuracy is important to you, then you should pay attention to this next section. You may want to measure something to the nearest thousandth or hundred thousandths. It is imperative that you pick a micrometer that fits your accuracy importance. Nothing is worse than you wanting to have a particular measurement, but your micrometer can’t be as accurate as you need. Knowing this beforehand will save you a lot of extra time and effort. A brand like Starrett will give you the best accuracy, but they are the most expensive micrometer brand to buy.
Digital v. Standard
When it comes to reading your measurements, the most accurate micrometers use either a digital or standard screen. Digital screens use an LCD screen to show the measurement reading. Because this portion is electrically based, you can imagine that it will eventually become obsolete, but not for the first couple of years.
For standard options, you will have to read the measurement on the sleeve itself. If you take good care of the standard micrometer, you can expect your device to last for an extended period of time. Some consumers have even said that their standard micrometer has lasted for 50+ years. Additionally, they will continue to give an accurate reading year after year.
Tips for Maintenance
Since micrometers allow for exact measurements, it is important that you keep device clean and tuned-up at all times. Some of the maintenance tips include oiling, cleaning, and securely storing.
To oil your micrometer, you should do this twice per month. Just a tiny amount of oil that is all-purpose will do for your micrometer. When fighting against rust and corrosion, this process is imperative for your micrometer having a long-lasting life. If you do plan to store your micrometer for long periods of time, oil the micrometer’s internal thread, so the bare bones of your device will not expire.
Cleanliness is also essential when owning a micrometer. To avoid corrosion, wipe down your micrometer before and after you use it. A lint-free, dry cloth works best in this situation. As you keep your micrometer away from long-standing dirt and grim, you will continue to ensure an accurate reading each and every time.
The last maintenance point involves storing the micrometer in a safe place. For as durable as a micrometer is, they are fragile devices. When they are not being used, they should find a home in a well-ventilated room that is about room temperature. This way, by avoiding damp areas, a micrometer’s life will stay strong use after use.
Different Types of Micrometers
When picking the best budget micrometer that money can buy, it is necessary to know the different options for you to try. You must know the difference between an outside, inside, and depth micrometer, as well as a v-anvil and tube micrometer.
- 1. Outside Micrometer
A micrometer that is used outdoors is great for blocks, wires, and piping. They can measure items thinner than a piece of paper, as well as something that is a few feet in width.
- 2. Inside Micrometer
Micrometers for inside use are exception inside tubes or homes. They are specifically manufactured as caliper micrometers to perform a specific task that deal in this area.
- 3. Depth Micrometer
A depth micrometer does measuring work for steps, teeth, and slot when working to get the job done right. These devices are sold in sets, which usually have interchangeable rods. This way, you can essentially measure anything you want.
- 4. V-Anvil Micrometer
A v-anvil micrometer is great for outside measurements when cutting heads. When using a v-anvil micrometer, these devices need pinpoint accuracy, or problems will start to arise.
- 5. Tube Micrometer
Are you in need of measuring the thickness of a pipe or tube? A tube micrometer is a right choice for you. The measuring anvil is rounded, which allows for a point of contact with whatever object you need gauging.
Different Sizes of Micrometers
For the past 100 years, complex mechanical systems have worked to improve measurements’ accuracy. For outside micrometers, they range from 0 to 12”. Each increment is measured in 1”, and it is accurate up to four decimals. When it comes to depth micrometers they come in 1” varieties and their accuracy is unparalleled.
Differences Between A Caliper and A Micrometer
When it comes to a caliper vs. a micrometer, there are a few differences that you should be aware of. First, the structures are different in nature. A caliper is built like a gun, while the micrometer looks more like an ax. In terms of least count, the caliper measures lowest at 0.1 mm and the micrometer lowest markings are at 0.01 mm.
Calipers use a unique jaw type construction that is perfect for internal and external measuring. On the other hand, a micrometer uses a screw gauge for measuring the outside of materials. However, this device is not as good when measuring internal materials.
For calipers, a zero error elimination process can happen by subtracting and adding the differences together. In the end, this will create an honest measurement. The same errors cannot be found with a digital micrometer.
How to Use A Micrometer
When learning to use a micrometer, you have to make sure you follow these steps before beginning. First, get to know a micrometer’s anatomy. The 7 key parts include a ratchet stop, sleeve, anvil, spindle, thimble, thimble lock, and frame. The ratchet stop is at the base of a micrometer. The sleeve is the component right next to the thimble. The anvil is one area where you put the material next to when measuring. The spindle is what can move closer or further away from the material, while the thimble lock holds the material in place when measuring. The frame is the body that holds the material underneath, so it does not get away for an inaccurate reading.
After you familiarize yourself with the best micrometer it is time to clean the device before you use it. By using a cloth, or clean piece of paper, put it amid the spindle and the anvil. Twist the cloth back and forth, while you tighten the micrometer. This will make sure that you can get a precise measurement before you even begin. Not only is this for practice, but also to ensure your device is clean without any abnormalities.
Now, it is time to start measuring. Start by holding the object you want measuring in your left hand. The material should also be up alongside the anvil. With the anvil stationary, you will be able to take on the most pressure, rather than the spindle piece, which could easily break. Be sure that the object is not moving because it could scratch your micrometer.
Your right hand should be holding the micrometer during this portion. The palm of your hand can hold the frame steady, or you can fasten the device to something stationary, like a table or workbench. If you go this route, you will be able to have a more hands-free setting.
The ratchet should be spun counterclockwise; also, make sure that the thimble is lined to 0. You can check this by looking at the sleeve scale. Continue to twist until the material is lined up snug next to the spindle. With enough force, the thimble will actually click. When you hear 3 clicks that are traditionally a stopping point to be proud of.
A thimble lock can then be used to keep the material still in the micrometer. The spindle can still be moved, however, even in lock mode. After you have locked the measurement, you can slide the object out-of-place. Do this carefully, so no scratches will come to your precious micrometer. Additionally, a scratch can even ruin the accuracy that you are trying to go for.
When you are done removing the object, right out your measurement. As you finish, make sure to clean your micrometer before you put it away, too. This way, you can assure that your micrometer will be ready to go the next time around.
FAQs: Frequently Asked Questions About Micrometers
Q-1: How important are precision and accuracy when measuring?
- Precision and accuracy are important, but they do not need to be focused on simultaneously to get the best reading. In certain cases, you may want one or the other. However, the best reading has precision and accuracy aligned together. When you see the value you have measured, you should check the reading again for best results. This way, you will be striving for the best of both worlds.
Q-2: How do I set a dial bore gauge with a micrometer?
- This is one of the most common methods when measuring on a micrometer. But, this is tricky when completing this on your own. A vise maybe your best friend, in this case, to help you stabilize. With the vise holding the micrometer down, you can use your hands to dial out the bore gage. Also, make sure to put a cloth for padding down when using a vise.
- Some even vise the gage itself, while they hold the micrometer on the other hand. Both are tricky, but find what is easiest for you to perform. Then, you can get the most accurate readings.
Q-3: What is a graduation mark and are they needed with a micrometer?
- With a micrometer, unless the product is digital, there will be graduation marks. These can be printed, engraved, or etched on. Most are not painted or scribed on the micrometer because this will wear off a lot easier than the alternative. Each micrometer brand will have their own preference, but make sure you have graduation marks that last. It is imperative to have these marks, so you can make sure your readings are as accurate as possible.
Q-4: How often does a micrometer need to be calibrated?
- When it comes to calibration, it really depends on what you think is best for your produce. Some do this every year, while others do it even more regularly, especially if they are using the product daily.
Q-5: What are the pros of using a micrometer?
- As one of the best precision tools on the market to-date, micrometers are very accurate when measuring. They can measure directly to the 100 thousandths place, especially with digital varieties. Micrometers are a reliable piece of machinery because of the uniform pressure that they use time after time. The scale functions perfectly together while being made of durable materials that will not wear out.
Q-6: What are the cons of using a micrometer?
- Best micrometers have their cons, too. With a limited range, this can be frustrating when you need it to measure something bigger than it presently can do. Larger objects to measure usually call for a bigger micrometer, which can cost a whole lot more. Also, some jobs call for a specific kind of micrometer and that can mean the micrometer you are using is obsolete just because of the line of work.
Q-7: What factors impact accuracy?
- There are many factors that impact accuracy, but the skill of the user is the most important. This is really why the operator needs to know what type of caliper is best for them. It could be the difference between good and bad measurements. Let us say you decide to go with a caliper that does outside measurements that you do not know how to use it properly. Your accurate measurement will struggle when measuring because of your limited understanding. Also, if your micrometer is not calibrated enough, this will factor into the problem, too. Lastly, make sure you zero point is online because this can cause an error, too.
At the end of the day, you have to find the best micrometer that works for you. Not everyone likes the same features or the same brand. But, you can find something that makes your life easier when measuring. So, take your time and start investigating. Even give a few micrometers a test run and then go with your mind and your gut. This way, you will have found a product that will make you happy and satisfied. Good luck getting as accurate as possible with your next micrometer. Also, check our latest review of Multimeter.
