The determinations are either performed by establishing calibration curves or by performing standard additions, both of which can be automated
With the 781 pH/ion meter you can measure pH values and determine the content of different ions using ion-selective electrodes.
The determinations are either performed by establishing calibration curves or by performing standard additions, both of which can be automated with an attached 765 or 776 Dosimat.
For the fully automatic standard addition you need only enter the concentration of your standard and the desired number of additions, the rest is taken care of by the pH/ion meter.
Any name can be used for the determined species and the result unit is freely selectable. Measuring ion concentration by means of direct measurement, standard additions or sample additions.
Inherent quality control tool: pH electrode test for standard electrodes, gel electrodes and electrodes for non-aqueous media.
Graphics display grants overview and facilitates operation.
Calibration with automatic buffer recognition, up to 9 calibration buffers.
Recall of stored calibration data including curves.
Plot function pH, U, T, Conc versus time on printer.
Result memory for up to 100 results. Stirrer control by the pH meter ensures reproducible measuring results.
Entering of calibration interval with reminder. Automatic recognition and control of stirrer via Metrohm serial bus.
