ZDJ-5 Automatic Titrator

  Instrument functions:

u   Touch screen, English office operation interface for easy use.

u   Its screen is 5.7 inch large and can show titration curve, first derivative and graphics. Also, it can edit and modify titration modes.

u   It has modular design and is composed of volumetric (coulomb) titration device, controlling device, measuring device which can realize potential titration, conductivity titration and constant titration.

u   Potential titrator is composed of volumetric titration module, controlling module and potential measuring module.

u   Conductivity titrator is composed of volumetric titration module, controlling module and conductivity titration module.

u   Constant titrator is composed of volumetric titration module, controlling module and constant measuring module.

u   Coulomb Titrator is composed of coulomb titration module, controlling module and potential measuring module.

u   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.

u   The instrument can be connected with TP-16,TP-24 and TP-40 serial printers and print measuring data, titration curve and calculation results.

u   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.

u   Different sensors can be chose to conduct acid base titration, redox titration, precipitation titration, complexometry titration, non-aqueous titration and pH value measurement.

u   The stirring system adopts PWM modulation technique and applies software to reduce the noise.

u   The titrator adopts the specific material which is against perchloric acid corrosion and can conduct several titration reactions.
