What are the advantages and disadvantages
Useful for measuring tricky dimensions
Spring joint calipers can be used to measure the dimensions of objects which cannot easily be measured with other tools such as a ruler.
Measurements can be taken quickly
They allow measurements to be taken quickly, and using a spring joint caliper can help to save time.
Accurate and reliable
If the user is aware of the limitations of its limitations, a spring joint caliper can provide a high degree of accuracy and reliability.
Useful for measuring large distances
Spring calipers are especially useful when measuring large distances.
Their measuring range is greater than that of most vernier and dial calipers.
Easy to maintain
Unless they are misused, spring calipers require little maintenance apart from the occasional oiling or parts.
Another measuring tool is required
Since they do not have a scale of their own, spring joint calipers must be used alongside another measuring tool such as a ruler or micrometer.
Not accurate compared to other types of calipers
Spring joint calipers are the least accurate type of caliper. The accuracy of readings is limited by that of the other measuring tool.
Multiple measurements are required
It can take practice to get a feel for this kind of caliper. Measurements should be taken at least twice to ensure that they reliable.
