module and constant measuring module.
7.Coulomb Titrator is composed of coulomb titration module, controlling module
and potential measuring module.
8.It has pre-titration, preselected endpoint titration, blank titration and
manual titration modes. The user can also create specific titration modes to
meet different experiment requirements.
9.The instrument can be connected with TP-16,TP-24 and TP-40 serial printers and
print measuring data, titration curve and calculation results.
10.The instrument is controlled by the computer. The real-time potential curve,
first derivative, second derivative diagram can be shown on the screen. If
matched with Rex specific titration software, it can conduct titration analysis,
realize editing, modification of titration methods. It also functions as storage
of titration curve and data, editing of titration calculation, dealing of
database and statistics.
11.Different sensors can be chose to conduct acid base titration, redox
titration, precipitation titration, complexometry titration, non-aqueous
titration and pH value measurement.
12.The stirring system adopts PWM modulation technique and applies software to
reduce the noise.
13.The titrator adopts the specific material which is against perchloric acid
corrosion and can conduct several titration reactions.
