780 pH Meter 781 pH/Ion Meter

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 This 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...

Stirrers The stirrers are 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 The package of the 780 pH Meter and 781 pH/Ion Meter contain the 6.0258.600 Unitrode pH electrode with integrated Pt1000 temperature sensor....

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 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...

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 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....

Graphics display grants overview and facilitates operation Recall of stored calibration data including calibration curve Memory for measured values accommodates up to 100 data sets Stirrer control by the pH meter ensures reproducible measuring results Inherent quality control tool: pH electrode test for standard electrodes, gel electrodes and electrodes for non-aqueous media Calibration with automatic buffer recognition, up to 9 calibration buffers Measuring ion concentration by means of direct measurement, standard additions or sample additions. Automation using a Dosimat plus turns...

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 Dosimat plus. 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...
