Buying Guide for the Best Calipers

Calipers are precision instruments used to measure the distance between two opposite sides of an object. They are essential tools in various fields such as engineering, metalworking, woodworking, and even in medical applications. When choosing a caliper, it's important to consider the specific needs of your tasks to ensure you select the right type and features that will provide accurate and reliable measurements.
TypeCalipers come in different types, including vernier, dial, and digital calipers. Vernier calipers have a scale and require manual reading, which can be precise but may take practice. Dial calipers have a dial that shows the measurement, making them easier to read than vernier calipers. Digital calipers display the measurement on an electronic screen, offering the easiest and quickest reading. Choose vernier calipers if you need high precision and are comfortable with manual reading. Dial calipers are suitable for those who prefer a mechanical display, while digital calipers are ideal for quick and easy measurements.
Measurement RangeThe measurement range of a caliper indicates the maximum distance it can measure. Common ranges include 0-6 inches (0-150 mm), 0-8 inches (0-200 mm), and 0-12 inches (0-300 mm). For most general purposes, a 0-6 inch caliper is sufficient. If you need to measure larger objects, consider a caliper with a greater range. Choose a range based on the typical size of the objects you will be measuring.
Accuracy and ResolutionAccuracy refers to how close the caliper's measurement is to the actual value, while resolution is the smallest increment the caliper can measure. Higher accuracy and finer resolution are important for tasks requiring precise measurements. For example, a caliper with an accuracy of ±0.001 inches and a resolution of 0.0005 inches is suitable for high-precision work. For general use, a caliper with an accuracy of ±0.01 inches and a resolution of 0.01 inches may be sufficient. Choose based on the level of precision required for your tasks.
MaterialCalipers are typically made from stainless steel, carbon fiber, or plastic. Stainless steel calipers are durable and resistant to corrosion, making them suitable for heavy-duty and long-term use. Carbon fiber calipers are lightweight and also resistant to corrosion, but may not be as durable as stainless steel. Plastic calipers are the least durable but are lightweight and suitable for less demanding tasks. Choose stainless steel for durability, carbon fiber for a balance of weight and durability, and plastic for light-duty applications.
Additional FeaturesSome calipers come with additional features such as data output for transferring measurements to a computer, depth gauges for measuring depths, and thumb wheels for fine adjustments. These features can enhance the functionality and ease of use of the caliper. Consider what additional features might be useful for your specific needs. For example, if you need to record measurements digitally, a caliper with data output would be beneficial. If you frequently measure depths, a depth gauge would be useful.
