Digital Caliper Buyer’s Guide
Like all tools designed to measure different values, you can’t rely on any random set of digital calipers to be as reliable and accurate as you’re expecting them to be. There’s always a chance that the calibrations might be off, or they don’t convert between measurement types correctly. This means they won’t meet your needs. Fixing these problems yourself wastes valuable time you could be spending on much more important tasks. That’s why you need the best digital calipers.
If you’re buying a pair (whether for yourself or work), it’s good to know which features and functions you should focus on first. Simply purchasing the first pair you see will often leave you with a poor-quality product, or even one that’s unsuited to the job you need it for! This results in a poor performance. The last thing you want to do is waste your money on an instrument that’s not suitable for you.
Consider these factors before you purchase:
While you can’t usually tell how well-calibrated a set of calipers will be, you can still look at the distributor’s website to see if they talk about the calibration process. Ideally, you’ll want a pair that’s already calibrated, especially if you’re entirely new to using digital calipers or need to use them straight out of the box. Bad calibration will also throw off your measurements and can even lead to serious mistakes further down the line if you don’t realize they’re wrong.
This is especially important for jobs involving small but vital components since you might not be able to judge whether your measurements are correct through sight alone. You can’t correct them until you know they’re wrong, so it’s best to avoid poor calibration altogether.
While it’s much rarer, knowing that a company claims to have calibrated their calipers can also give you some legal grounds if something goes wrong. If a poorly set-up caliper leads to something important getting destroyed, especially in the workplace, you won’t be responsible for the mistake.
Be aware that models with calibration certificates may cost more.
Alongside calibration, there’s also measurement accuracy to consider. Not all calipers will display measurements to the same decimal point. This is due to the different hardware components in the caliper. There can be a big difference between 0.1 mm and 0.01 mm when you’re dealing with small objects. While this might not be too important for DIY work, it can make a massive difference in industrial and construction work, especially when a situation calls for measurements that are too specific for you to measure properly.
Some of these instruments won’t provide certain measurement types, either. While it’s rare to find one lacking either metric or imperial in some way, they won’t always convert between types well. They might even be missing alternative measuring systems (like fractions) that could be vital to certain plans or instruction manuals. Even if you can convert between unit types yourself, it still wastes time and takes more effort to achieve the same result.
This can also apply to the zero setting if that particular caliper has them. While this setting makes it much easier to compare different measurements, it still uses the same calibrations as regular measurement styles. Making sure these measurements are correct is just as important as when it comes to standard measurements.
Some models have a driving wheel for your finger, which makes it easier to make smaller adjustments.
While measuring the distance between two points is important, there’s no one way to do this. Ideally, the best digital calipers will measure both the inside and outside of a chosen section. Some will also have a step measurement feature. Specific designs use a pull-out depth-measuring stick for judging how deep a hole or dent is in a surface. This is great if you work with a variety of depths.
Not all of these are necessary, especially if you’re only using your calipers for a very specific purpose. Still, they can make a big difference if you’re into DIY or need them for a professional job. Being able to measure in more ways opens up more opportunities to check for mistakes, improving the quality of whatever you’re building without forcing you to buy entirely new tools.
A zero setting can also make a difference since it allows you to compare two measurements without recording them separately. While it’s not particularly challenging to do this, it still saves plenty of time and can help you avoid measurement mistakes by showing you the comparison directly.
As with all tools, water, rust, temperature, and other types of damage can lead even the best digital calipers to become unreliable and harder to use, especially if important components become damaged. Water can be a big problem for metal tools, as can other liquids like oil or cleaning chemicals. There’s rarely any downside to choosing a set of calipers that offer great resilience against common types of damage.
This is especially important if you’re using them for tasks where damage is likely, such as repairing cars, pipes, large machines, or anything else that causes damage to both you and your tools if mishandled. While it’s definitely better to break your tool rather than part of your body, it still leaves you stuck without an important piece of equipment.
Always check out the product reviews to see what customers had to say about the product’s durability. Trusted brands are more likely to be more durable and last longer.
There’s also the issue of having to replace it. For example, a cheaper caliper without extra protective features might break more often, and the cost of constantly buying a new one will quickly add up. In contrast, a slightly more expensive set with additional features such as a locking screw might last much longer while costing less overall.
You may want to check whether the tool you’re looking for has a warranty. This way, if anything goes wrong, they can simply send you a replacement product.
Calipers with zero settings might sometimes expect you to reset it using the same button. Move the jaws back into the zero position and hit the button again to bring the measurements back to normal.
The material of your caliper will affect its durability. Most calipers are made out of either carbon fiber, stainless steel, plastic, or composite. A general rule is that stainless steel frame or a model with carbon polymer fibers will be more durable than a plastic one.
Some models will come with a IP54 rating or even a IP54 protection certificate. IP protection (also known as ingress protection) will ensure your model is resistant to damage from water, dust and dirt. This is a great advantage if you’re using your caliper for professional work or working in harsh conditions.
Some brands like Vinca will come with an Rs232 data transfer port or a USB cable to send information over to your computer.
Did You Know?
Some digital caliper models with power-saving modes will only activate them when the jaws are reset. This can either be when they’re closed or fully open, so check with the manufacturer’s instructions to avoid wasting power.
Just be careful with your dial caliper because if they are dropped, the rack and pinion system can get out of alignment and it can be difficult to recalibrate.
