Metrohm, 2.781.0010, 781 pH/Ion Meter

In addition to pH, ion, voltage and temperature measurement, the combined 781 pH/Ion Meter also offers an automatic stirrer control, a multi-point calibration with up to nine buffers (pH mode), a method memory and various monitoring functions. The automatic pH electrode test in conformance with GLP permits objective assessment of the electrode. The large backlit multi-line display provides an overview and makes the individual settings easy. The bi-directional RS-232 interface enables data transfer to a printer or PC.Three different modes are available for ion measurement: direct measurement, standard or sample addition. In the case of fully automated standard addition with an optional Dosimat, only the concentration of the standard and the desired quantity of addition steps need to be entered, the pH/ion meter takes care of the rest. Up to 19 standards can be used for the calibration for direct measurement.
