water determination with the titrando karl fischer titration the karl fischer water determination is one of the most frequently applied laboratory methods in contrast to other water determination methods it is specific as well as rapid and requires no expensive equipment with an application range of 0.1 to 100 water the volumetric karl fischer titration is used in a wide variety of fields no matter whether you determine the water content in food cosmetics or pharmaceutical products the 841 titrando is always the right instrument the sophisticated control algorithm of the titrando has been adapted to the characteristics of the karl fischer reaction and guarantees highly precise results you can choose between a polarized alternating current ipol or a defined voltage upol to be applied to the electrode both working modes yield fast and precise results different reagents require different parameters the 841 titrando lets you select the appropriate method for each type of reagent combined w

karl fischer alone is not enough the set mode the 841 titrando also disposes of the set mode which means that potentiometric titrations to a preset endpoint ph value or potential can be performed typical applications of the set mode are the determinations of p and m values in water analysis ph meter included besides the measuring input for polarized electrodes the titrando also has two electrode inputs for ph and reference electrodes the resolution of the measuring inputs is 0.001 ph and thus identical to that of our precision ph meters ready-for-use methods for ph measurement as well as for electrode calibration are stored in the instrument in addition the electrode characteristics and the «calibration history» of each sensor are memorized naturally as with any ph meter you can also measure the potential and temperature 8

reagent dosing à la carte the space-saving dosino titrating means dosing intelligently with the 841 titrando you dose with dosinos and dosing units that are attached directly onto the reagent bottle this means that dosing requires no additional bench space thanks to adapters any reagent bottle can be used directly the dosino houses the latest state-of-the-art electronics and micromechanics the dosing unit can be exchanged within seconds thanks to its transparent housing any bubbles that may be present in the dosing cylinder can be seen immediately and the valve position is always shown rinsing and preparation of the dosing unit can be carried out automatically manual dismantling and cleaning are not necessary the dosino the optimal kf dosing system thanks to the «empty» command the dosino can be emptied completely this avoids the cumbersome opening and cleaning of the dosing unit once the reagent is used up the remaining content of the cylinder can be transferred directly to the bott
