Professionals of all kinds need to be able to measure things. Whether you are a mechanic, engineer or electrical technician, the need to accurately take measurements is important. In years past, rulers, tape measures, and other manual measurement devices were the only option. Vernier and dial calibers were popular models for many years. As technology has advanced, however, digital calipers have become one of the hottest measurement tools on the market.
As with most tools, there are several things you should take into consideration before purchasing a digital caliper. First, you should take into account the quality of the materials used to build the calipers. Digital calibers come in various materials, like stainless steels, carbon fiber, plastic and composites. Most experts will agree that stainless steel is the way to go as it is naturally water, stain and dirt resistant. (If dirt, dust and water is a concern, look for a model that comes with ?IP54 Protection.) Digital calibers typically come with a small display that shows you the computerized measurement being taken. The size and screen type, like LCD, are features you may want to take into account. The larger and clearer the screen, the easier it will be for you to read the measurements it displays. Caliper length is another thing you might want to consider. Digital calipers come in sizes that range between four and forty-eight inches. Depending on your use requirements, the length can be a major factor in your purchasing criteria. Battery life is another feature you may want to consider. Many models now come with an automatic shut off function that can help to preserve battery life. Cost is always a personal factor as well. Ultimately, an easy to use caliper that has smooth jaw movement, a relatively sensitive thumb wheel and a display you can clearly read is ideal.
Our Top Recommended Digital Calipers
Now that you know what you are looking for, let us take a look at the actual models we recommend.
Calipro Digital Caliper (Model No. 100)
The Calipro digital caliper is a hardened stainless steel product capable of taking measurements between zero and six inches. Able to be zeroed out at any time, measurements can be easily displayed in inches or metric units. The large LCD screen makes readings easy. Not only does this model measure both interior and exterior scope, it also comes with depth probe.
The Calipro digital caliper is easy to use. The single-button switch helps you quickly transition between inches and metric measurements without much hassel.
Measurement may be erratic. The jaw does not slide as smoothly as some users had hoped and the dial is a bit stiff. Additionally, if you need fractions, look elsewhere. The Calipro digital caliper only displays decimals.
EAGem Digital Caliper (IP54)
The EAGem digital caliper is made from stainless steel. As an IP54 protected device, the EAGem is also water resistant. The single-button switch allows users to quickly select between inches, millimeters or fractions. In fact, this six inch digital caliper comes with a large, easy to read LCD display that is capable of showing fractional measurements up to 1/64. This digital caliper also comes with an automatic shut off function that will power down your caliper after five minutes of no use to preserve the life of the included 3V CR032 batteries.
