What is the difference between an indicator and a universal indicator?

What characteristics limit the usefulness of indicators?
Chemical indicators measure the pH directly Chemical indicators are highly expensive They must be chosen for a specific pH range Chemical indicators cannot determine the exact value of pH of the solution
