pH Measurement of Bioethanol

The pH value is an important quality criterion for all biofuels. A combined pH glass electrode with ground-joint diaphragm is recommended for measuring the pH in organic solvents. Because of the expected low conductivity of the sample, the electrode should be particularly well shielded in order to suppress electrostatic influences.
The pH meter used for the measurement should possess the following GLP functions, among others:

pH Measurement by Metrohm

The EtOH-Trode with special membran glass and ground-joint diaphragm is particularly suitable for measuring the pH of bioethanol. It's double junction system gives the free choice of electrolyte (different in different norms).
The pH meter 827 pH lab for laboratory use and the handy, battery-operated 826 pH mobile offer all the required functions with extremely comfortable operation.
