How should maintenance be for maximum performance and long life span during operation of emulsions?

In order to get maximum performance and long effective life span from emulsifiable cutting fluids during operation they have to be renewed regularly. Concentration and pH rates of emulsions should be daily checked and recorded. PH measurement can be done by pH papers and digital pH meters. PH paper is proper for daily pH measurements but a calibrated electronic meter should be used for more definite results in detailed monthly tests. Daily concentration tests can be easily done by refractometer. On the other hand emulsions get contaminated with foreign substances and this causes lapses in refractometer measures. Thus, concentration test should be applied with acid extrication method at least once a month. Any user can easily make daily pH and concentration tests. But those tests are not sufficient for testing stability and operationality of emulsion and at least once a month specimen should be taken and particularly tested in manufacturer laboratory, results should be considered with i
