ZDJ-4A automatic potentiometric titrator

Product Information:

Model:

The instrument is a kind of intelligent laboratory volumetric analyzer, which is mainly applied to such industries as universities and colleges, scientific research institutes, petrochemical industry, pharmacy, drugs inspection and metallurgy.
Dot matrix LCD, Chinese operation interface
Can produce special titration mode by using pre-titration, presetting terminal titration or manual titration function.
Using different electrodes can make acid and alkali titration, oxidation reduction titration, deposition titration, complexation titration, nonwater titration and as well as the measurement of pH value
Power off protection function. Measuring data stored in the instrument and set parameters can be kept under the condition of closedown or off normal power cut.
Stirring system adopts PWM modulation technique, timing with software and low noise
The instrument is equipped with RS-232 interface, which can connect (TP-16, TP-24 or TP-40) serial printer to print can test data, titration curve and computing result
Communicate with computer by using REX DC Software of Data Acquisition. Display titration curve, and its first and second derivative and make contrastive analysis. In addition, can edit and modify the titration mode to realize remote control and make calculation of many kinds of statistical results.
