What a chemical sensor is expected to be

A chemical sensor is a self contained probe that provides in real time information about the chemical composition of its surroundings.

To this end, it has to perform two functions:
An example: the glass electrode (in conjunction to a reference electrode) is able to recognize the hydrogen ion by selective ion exchange. and gives rise to a cell voltage that  is a function of hydrogen ion concentration.

Applications

An application: Measuring pH in meat
 
Measuring pH in slaughtered meat is a good way  to monitor product quality. A lance-shaped ISFET probe (Sentron), with a large handle for good  grip, is an ideal solution for fast, accurate and most of all, safe measurements. More>>
