Linear measurement is the measurement of Diameters, Lengths, Thickness, Heights and also which are includes internal measurements and external measurements.
The Linear measurements are classified into Two types they are.
- Precision Instruments.
- Non – Precision instruments.
Linear measurements of Precision Instruments
The precision instruments are following to possess high degree of accuracy in measuring the dimensions. The instruments used for measuring the angles and Types of Plain Limit gauges.
- Vernier Calipers
