Angular Measuring Instruments are the devices that are used to measure the angle of the given specimens. Types of Angular Measuring Instruments: There are various types of Angular Measurements which are based on various standards, and those are the following: Line Standard Angular Measuring Devices Protractor Universal Bevel Protractors Face Standard Angular Measuring Devices Sine […]

Linear Measurements: Definition, Standards, Methods & Instruments [PDF]

Metrology is defined as the science of measurements or the precision of measurements. Even it can be defined as the accuracy of measurements. The science which is dealing with measurements and their conditions is called measurement science or metrology. In this article, we will discuss Methods, Standards, and Instruments for Linear Measurements. But before that, […]
