Titration modes, guided operation and data handling
DET and MET modes
DET mode supports dynamic equivalence point titration, while MET mode supports monotone equivalence point titration
with defined dosing behavior. These modes are useful for endpoint discovery, method validation and repeatable titration programs.
SET and MAT modes
SET mode stops titration at a preset pH or mV endpoint. MAT mode gives the operator manual control while the instrument
records the pH/mV response, which is practical for training, method development and electrode checks.
GLP-oriented records
TITRO4 stores up to 50 titration data sets and the latest titration curve. RS-232 and USB/RS-232 PC control support
practical reporting, method supervision and laboratory documentation.

Selecting the right titration configuration
When selecting the TITRO4 automatic potentiometric titrator, the method, electrode set, burette volume,
reagent chemistry, endpoint criterion and sample preparation should be matched to the target application. Acid-base,
precipitation, redox and complexometric titrations may require different electrodes, reagents and accessories.
COLO.Science can support selection of electrodes, burettes, reference solutions, pH buffers, titration accessories and
documentation so the final configuration matches the laboratory method and quotation scope.
TITRO4 automatic potentiometric titrator for routine laboratory titration
The TITRO4 automatic potentiometric titrator is useful when a laboratory needs an automated platform for
pH/mV endpoint titration, repeatable burette dosing and structured titration records. Its DET, MET, SET and MAT modes give
laboratories flexibility for routine methods, method optimization and operator-guided titration work.
In practice, titration quality depends on the titrator, electrode condition, calibration, reagent concentration, sample matrix,
endpoint settings and laboratory SOP. TITRO4 provides the measurement and dosing platform, while COLO.Science can help define
the correct electrodes and accessories for the final application.
