Comparators:- There are certain devices in which the standards are separated from the instrument. It compares the unknown  length with the standard. Such measurement is known as  comparison measurement and the instrument, which  provides such comparison, is called a comparator. Comparators are generally used for linear measurements,  and various comparators available differ basically in the  methods employed for amplifying and recording the  variations measured.

Functional Requirements:- a. High degree of accuracy and precision b. The scale should be linear and have a wide range c. High amplification d. Good resolution e. Comparator should be versatile
