Description :

　　ZDJ-4B automatic potentiometric titrator

　　ZDJ-4B automatic potentiometric titratorMain Features

　　1. Integrated compact titrator design, convenient automated titration system

　　a) Integrated design of valve burette, easy to replace, avoiding interference between different solutions during titration

　　b) Automatic identification of pH standard solution group, (standard solution group 1: 4.00 pH, 6.86 pH, 9.18 pH; Standard solution group 2: 3.78pH, 7.00pH, 10.01pH), also supports manual identification

　　c) Support setting system time, operator number, burette type, burette coefficient, mixer speed, manual temperature, and calibration potential zero point value.

　　d) Titration endpoint reminder

　　2. Measurement information that complies with GLP standards, with complete traceability information

　　a) Support storing 200 sets of titration results and 1 set of titration curve

　　b) Support data deletion, retrieval, printing, or output

　　c) Complete record of titration mode, titration type, titration start time, titration end time, operator, stirring speed, burette type, burette coefficient, titrant concentration, sample volume, endpoint number, and related concentration values

　　3. Firmware version upgrade function, reducing your titration costs and making your operations more efficient

　　a) Through software upgrade, it is possible to connect to an automatic sampler and improve the extraction rate

　　4. Titimeter control mode: dot matrix LCD display, button operation, computer Chinese software for simultaneous or separate control

　　5. Real time display of testing methods, titration curves, and measurement results

　　6. It has pre titration (dynamic titration), preset endpoint titration, and mode titration (two modes of titration are randomly provided: a. HCl → NaOH (0.1mol/L), b. K2Cr2O7 → Fe2+(0.1mol/L).)

　　7. Multiple titration modes such as titration, manual titration, pH measurement, etc., supporting the generation of titration modes, allowing users to create 8 more titration modes

　　8. Equipped with power-off protection function

　　9. USB interface, RS-232 printing interface, randomly matched titration software instrument, can be connected to a PC through USB interface, and the titration curve and its first and second derivatives can be displayed in real time on the computer. Convenient for editing and modifying titration modes, and capable of statistical analysis of results

　　10. Support restoring factory settings
