If you are truly looking for the best micrometer, then one thing you have to know is the type. It’s very important because it affects the success of your measurement. Since the micrometer is designed for specific purposes; not really a purpose though, taking a wrong micrometer will likely lead to unaccepted measurement. For example, … Read more

Micrometer and caliper are both linear measuring tools that we can encounter easily in machine shops. Both are designed for accurate and precise measurements. They measure the linear distance of an object such as length, thickness, (inside and outside) diameter, width, depth, etc. As long as you can clamp the object properly, you measure accurately. … Read more

Reading vernier caliper takes more steps than reading dial caliper or reading digital caliper. The users have to manually calculate both the scales (the main scale and the vernier scale). Vernier scale calculation, especially, is the contrasting thing when compared to reading those two types of caliper. Your eyes have to be careful when deciding … Read more

Learning about how to read a dial caliper is about learning how to read its main and dial scale. The main scale is linear like the ruler, while the dial/secondary scale is circular. Simply, if you ask how to read dial caliper, you have to master these two scales. There is an imperial or metric … Read more

Reading a dial indicator means calculating or interpreting the value shown by the scales. The calculation or interpretation results in an easy-to-understand number. Basically, reading a dial indicator is easy. All you have to do is simply adding the reading value of the inner scale and the outer scale. Inner Reading + Outer Reading = … Read more
