the convincing way of determining low water contents an innovative and comprehensive solution the 756 kf coulometer continues metrohm s established line of karl fischer instruments for the determination of low-level water contents despite its compact construction this instrument leaves no wishes unfulfilled it comes equipped with a built-in printer and two rs 232c interfaces which allow communication with a balance external printer and/or computer this latest addition to the karl fischer range guarantees accurate and reproducible results even for water contents in the lower micro range the dialogue languages english french german spanish portuguese swedish and italian are standard as is the backlit screen with its graphics capabilities the screen not only provides a clear presentation of the parameters but also shows graphically the course of the kf determination as µg water versus time this facilitates the assessment of the determination and is a great help in method development and v

easy operation 756 kf coulometer with 700 dosino for automatically aspirating the titration vessel contents and adding fresh reagent dosino and waste bottle are mounted on the 6.2055.100 bottle support flexible but easy to operate no contradiction in terms often it is felt that an instrument offering extensive capabilities cannot be easy to operate the 756 kf coulometer solves this problem by placing at your disposal an expert and a standard mode in the standard mode only those functions are accessible that are needed in routine work operation in this mode requires very few keystrokes and is extremely easy the user methods stored in the instrument ex works allow you to start your water determinations without further ado cell with or without diaphragm the choice is yours the 756 kf coulometer is available with two generator cell types the cell without diaphragm requires just one reagent and is virtually maintenance-free it can be used for a large number of applications the cell with

oven method with new possibilities 768 kf oven with additional features the 768 kf oven is used for samples that cannot be introduced directly into the kf cell the new heating tube guarantees an optimal temperature distribution in the sample compartment temperature control is very accurate when the 768 kf oven is used together with the 756 kf coulometer the oven parameters are queried by the kf-coulometer at the end of the determination and inserted into the result report thus apart from the two connecting cables no additional equipment is required to route the data to the built-in and/or a common printer 774 oven sample processor automation unlimited the 774 oven sample processor allows the application of the oven method to a series of liquid or sol 756 kf coulometer with 768 kf oven id samples typical samples are crude oil and oil products such as hydraulic oils multigrade oils and used oils as well as organic amines toners plastics pharmaceuticals and freeze-dried products sample
