Indicators change the colours when the PH of the sample changes. So during titration when the reaction is complete a new product will form which is resulting in sudden change of PH. This can be detected by the change in the colour of the sample. The reaction may be neutralization reaction or Redox reaction. So to know the exact stoichiometric quantity of reagents to complete a reaction we must use Indicators. different indicators give different colours based on the PH.

'Conductometric' IS a special case of volumetric analysis, it's the way of measuring the endpoint of titration. An other method is 'potentiometric' by measurement of pH.
A form of volumetric analysis in which the formation of a colored complex is used to indicate the end point of atitration.

AnswerVolumetric analysis or titration is a common laboratory method of chemical analysis which can be used to determine the concentration of a known reactant; volumetry is a quantitative method of analysis.Qualitative analysis is used to separate and detect elements, functional groups, molecules etc. in a sample substance, without specifying concentration.
When temperature increase the volume also increase; but if you think to volumetric titrations the effect is without importance.
Volumetric analysis (volumetry) is a largely used method in analytical chemistry based on the measurement of a solution volume.
Indicators
The pricipal use is in the volumetric titration - a method of quantitative chemical analysis.
