flexible and easy to operate the 780 ph meter and the 781 ph/ion meter combine the highest metrohm quality with advanced design ph meter and ion meter metrohm s new ph meter generation offers numerous possibilities in addition to the general functions for measuring ph potential and temperature the new ph meters boast features such as the optimized glp-compliant electrode test as well as monitoring and service intervals with the 781 ph/ion meter you can determine ion concentrations at a level of comfort offered only by metrohm 801 magnetic stirrer on the 781 ph/ion meter the 804 ti-stand with 802 rod stirrer offers an alternative way of stirring 2

stirrers not only the ph meters are new but also the stirrers have been optimized they are now directly controlled by the ph meter via the msb interface msb metrohm serial bus the stirring speed is set on the ph meter this assures that measurements are always carried out under the same conditions you can choose between the 801 magnetic stirrer and the 802 rod stirrer electrodes metrohm offers a large range of ph and ion-selective electrodes please find an overview of our electrode program under www.metrohm.com and additional information on ph measurement under www.ph-measurement.com the package of the 780 ph meter contains the 6.0232.100 ecotrode ph electrode that of the 781 ph/ion meter the 6.0258.010 unitrode ph electrode with integrated pt 1000 temperature sensor switch on and measure despite the many functions they offer operation of the new ph meters is easy after switching on the instrument you can immediately measure using the inherent standard parameters the large display acc

practical quality control unique glp-compliant electrode test for years metrohm as the only manufacturer worldwide has offered ph meters with glp-compliant electrode test with the new ph meters you can carry out a test that is specially adapted to your electrode type be it a ph electrode with aqueous non-aqueous or gel electrolyte the electrode test yields specific information such as response time zero point or slope as well as an overall statement that informs you about the condition of the membrane and the diaphragm ph calibration with automatic buffer recognition with the 780 ph meter and the 781 ph/ion meter you can perform ph calibrations with up to 9 buffers calibrations are made easy by the sophisticated user guidance automatic buffer recognition and evaluation you can store the calibration data including curve under the corresponding electrode identification and view it any time should you wish to use buffers different from those stored in the instrument you are free to do so

user identification thanks to the user identification you can always find out by viewing the report who performed which determination and at what time the user has also the possibility to confirm the results with his signature in the field provided for this purpose on the printout monitoring intervals forgot validation calibration or service interval expired with the new ph meters these are things of the past thanks to the integral monitoring functions you are alerted to the corresponding quality control tasks in time the intervals can easily be adjusted to your specific requirements each time the instrument is switched on it carries out an internal system diagnosis that ensures the correct functioning of the ph meter to complete the documentation you can issue this instrument test as a system report instrument test with 767 calibrated reference it occasionally happens that the displayed measuring value appears to be untrustworthy in these cases the reference values supplied by the 767

top-of-the-line ion meter easy and comfortable measuring of ion concentrations a metrohm exclusive with the 781 ph/ion meter you can determine the content of different ions using ion-selective electrodes the determinations are either performed by establishing calibration curves or by carrying out standard or sample additions both techniques 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 up to 19 standards can be used for calibrations evaluation of the calibration curves or of the additions is carried out automatically by the ph/ion meter you can obtain the following metrosensor ion-selective electrodes from us · with crystal membrane f cl pb2 cu2 ag s2 cn i br cd2 scn · with polymer membrane na ca2 no3
