The optimum analyser

There are more marked differences between process analysers than there are between laboratory analysers owing to the greater variety of requirements and experimental conditions involved in different industries. Despite their diversity, every process analyser should have a number of desirable features, namely  

In practice, process analysers do not have all of the above desirable features instead, they are a compromise between the requirements of the process to be controlled and affordability. 

With few exceptions, the development of process analysers Is one generation behind that of laboratory analysers. It is significant that many process plants are stiii controlled by pressure, temperature, flow or fluid level meters, easy to instal, calibrate and maintain. 

There are various reasons accounting for the long delay involved in the adaptation of well-known laboratory techniques to the control of industrial processes
