￭ MET
Monotonic equivalence point titration. The reagent is added in con-
stant volume steps.
Measuring modes:
– pH (pH measurement)
– U (potentiometric voltage measurement)
– Ipol (voltametric measurement with selectable polarization cur-
rent)
– Upol (amperometric measurement with selectable polarization
voltage)
￭ SET
Endpoint titration at one or two specified endpoints.
Measuring modes:
– pH (pH measurement)
– U (potentiometric voltage measurement)
– Ipol (voltametric measurement with selectable polarization cur-
rent)
– Upol (amperometric measurement with selectable polarization
voltage)
￭ STAT
Endpoint titration with constant maintenance of the measured value.
Measuring modes:
– pH (pH measurement)
– U (potentiometric voltage measurement)
￭ KFT
Volumetric water content determination according to Karl Fischer.
Measuring modes:
– Ipol (voltametric measurement with selectable polarization cur-
rent)
– Upol (amperometric measurement with selectable polarization
voltage)
￭ KFC
Coulometric water content determination according to Karl Fischer.
Measuring mode:
– Ipol (voltametric measurement with selectable polarization cur-
rent)
￭ BRC
Coulometric bromine index determination. Determining the amount of
double bonds in e.g. mineral oils.
Measuring mode:
– Ipol (voltametric measurement with selectable polarization cur-
rent)
