What are the advantages and disadvantages of vernier calipers?
There is a range of different tools available which are able to measure precise distances such as vernier calipers. This article looks at the advantages and disadvantages of using vernier calipers.
Advantages of Vernier Calipers
Accuracy and Precision
Vernier calipers provide accurate and precise measurements over a large range.
As the main scale and vernier scale are built into the tool, another measuring instrument such as a ruler or tape measure is not required.
Vernier calipers can be used to take a variety of different measurements. These include internal dimensions, external dimensions and depth measurements.
Most vernier calipers are made out of stainless steel. Since steel is a very durable material, with proper care, a stainless steel vernier caliper can last a lifetime.
Compared to other types of caliper, vernier calipers are relatively inexpensive.
Disadvantages of Vernier Calipers
Good Eyesight is Required
The vernier scale of a vernier caliper is quite small, and so can sometimes be difficult to read. It is not difficult to misread the last digit of your measurement. Good eyesight or a magnifying glass is required when taking readings.
Knowledge of Vernier Calipers is Required
As the vernier scale is a unique measuring instrument, users must learn how to read a vernier caliper before taking measurements.
Possibility of Errors
Taking a series of measurements one after the other can lead to reading errors, because concentration is required.
More Accurate Tools Available
Vernier calipers are not the most accurate precision measuring tool available. For example vernier calipers are not as accurate as digital calipers.
