Measuring instruments

There are many type of measuring tools which are used in workshop some of important tools are given below-

Steel scale

They are used to measure lengths and other geometrical parameters. They can be a single steel plate or flexible tape type tool.

Calipers

They are usually of two types- inside and outside caliper. They are used to measure internal and external size (for e.g. diameter) of an object. It requires external scale to compare the measured value.

Vernier calipers
It is a precision tool used to measure a small distance with high accuracy. It has got two different jaws to measure outside and inside dimension of an object.It can be a scale, dial or digital type vernier caliper

Speed Square
it serves as five tools in one, including: try square, miter square, protractor, line scriber, and saw guide. The markings will never fade, ensuring you'll be able to mark out correct angles on wood cuts for years to come. And the tool is light and strong.

Protractor

Protractors are the tools that help humans to measure angles.A protractor is a measuring instrument, typically made of transparent plastic or glass, for measuringangles. Most protractors measure angles in degrees (°). Radian-scale protractors measure angles in radians. Most protractors are divided into 180 equal parts.

Laser measure

The laser measure has become a go-to-tool for designers, architects, and contractors. It's also a great tool for homeowners to have on hand, as it instantly measures any distance for up to 50 feet. This laser measure from Bosch also features a continuous measurement feature that provides instant real-time results no matter where you point it.

Micrometer

There are several types of micrometers. A micrometer is used to measure diameters and depth when higher accuracy is demanded. It can give a reading to the accuracy of 0.001 mm.The measurements they provide can be more accurate than those given by other measuring devices such as dial calipers or vernier calipers, but depend very much on the user's care. 

Thread Pitch Gauge

 A thread pitch gauge is used to measure the threads on a screw. It has many thin blades each with a number which shows the distance between the threads.it is usually heat and trail method to measure the thread pitch.it is mostly used in industries.
