Buying Guide of Best Digital Calipers for Reloading
When you are looking for a suitable caliper for yourself, you should consider the factors listed below. These are very crucial factors that will guide you to make the best purchase.
The depth rod is the part of the tool that allows the caliper to measure the depth of the cases for reloading. Most digital calipers come with this additional accessory, but digital calipers do not include a depth rod.
It is also true that you might be in a profession which does not require this accessory. But even if you don’t need it, it never hurts to get an additional accessory.
Calibrating Digital Calipers
For calibrating, you can go for two options. Some calipers come pre-calibrated, and there are also now which can be manually calibrated
For beginners, it is best to get the pre-calibrated ones. In that way, they can learn the work first without worrying about calibrating the caliper manually.
- Manual Calibration
The manual calibrating ones are mostly preferred by professionals who have been doing their work for years. Because they are experts, they know the tool well. They might want to manually adjust their caliper to customize the tool. However, manual calibrating digital calipers are not suggested for beginners.
The accuracy of ratting is a very crucial factor when it comes to calipers. Since the tool’s primary function is measuring, the accuracy rating tells us how much the caliper reading will differ from the actual reading. Usually, the accuracy ratings range from 0.1mm to 0.4mm.
Since you want your calculated reading to be as accurate as possible, so it is always best to get the ones with a 0.1mm rating. This means the reading will differ only by 0.1mm from the actual calculation. You should go for the higher rating ones like 0.2mm or 0.3mm. But make sure you know what you are buying before you buy it.
You don’t want to buy something and realize after the purchase that it was a bad decision. You want something which will help you be more efficient and make your life easier.
Caliper Accuracy Chart
When looking for calipers, make sure you look for the one that comes with the accuracy chart. The accuracy chart is a very crucial thing for a beginner. It will guide you and give you a better understanding of the accuracy of the caliper.
The screw lock is another factor that plays a big role in the measurement part of the caliber. The screw is what holds the objects you measure in place. You have to place the object you measure between the jaws of the caliber.
Then the screw lock keeps the jaws fixed and keeps the object from getting loose. So when you place an object and place it between the jaws to get the measurement is accurate.
If the screw lock is not up to the mark, it might not keep the jaws fixed and firm.
The I.P. rating defines the durability of the tool. Durability is very important especially because it is a tool that you don’t want to keep on repurchasing.
Calipers will go through rough usage. You will be using it when you are working in your factory or workshop. You might even need to carry the product with another tool in a toolkit.
If the tool is not durable, it might get damaged by some other heavy tool. If the I.P. rating is not up to the mark, it might even break when measuring some items. It is not that uncommon. Many caliper’s jaws break if the IP rating is not up to the mark.
The unit the caliper is showing the calculations in is very important for you to work properly. If the unit is not set correctly, then it might create confusion amongst users. Most digital calipers calculate in metric or imperial units. There are also the ones that can calculate in both units.
You can switch from one unit to another unit easily in those calipers. Those are the ideal calipers. However, you should be careful while making the switch because it might mess up the calculations. It might show an inaccurate reading after the units have been changed.
A tool should always be comfortable to use. It should be easy to maneuver and work with. In the case of the digital calipers, the length makes the product convenient for the user.
When the length is short, you get less place to hold it properly. That is why get something which of appropriate sized. Then you will be able to hold it comfortably without covering the screen with your hands.
As mentioned before, a tool should always be durable. That is why it is very important for the caliper to be weather resistant. You might keep it outdoors or in a garage where there will be rain, snow, or too much sunlight. An extra layer of protection will increase the longevity of the product.
