main features
One The integrated design of compact titrator, automatic titration system convenient
A Burets) valve integrated design, convenient replacement, effectively avoid the interference between different titration using different solution
B Automatic recognition of pH) The standard solution group (group 1 standard solution 4.00pH, 6.86pH, 9.18pH; group 2:3.78pH, 7.00pH standard solution, 10.01pH), at the same time support manual recognition
C Support) to set the system time, operator number, type, burets coefficient, stirrer speed, burets manual temperature and correction of zero electric potential value.
D Remind) titration end point
Two In accordance with GLP The measurement information specification, traceability information more complete
A Support store 200) The results of titration and 1 sets of A titration curve
B ) support data delete, search, print and output
C A complete record of titration and titration) mode type, titration start time, end time, titration operator, stirring speed, burette type, burette coefficient, titrant concentration, sample volume, end point number, and the concentration of
Three Firmware upgrade function, reduce the cost of your titration, make your operation more perfect
A ) through a software upgrade, can be connected to the autosampler, perfect and improve efficiency
Four Titration control mode: liquid crystal display, key operation, computer software and Chinese control or control respectively.
Five Real time display of the testing method, titration curve, measurement results
Six With pre titration (dynamic titration), preset end point titration, titration (random mode provides two special mode a. HCl titration To NaOH (0.1mol/L), B. K Two Cr Two O Seven To Fe 2+? (0.1mol/L)).
Seven Blank titration, manual titration, PH measurement and other titration mode, supports the generation of special titration mode, allowing users to create the most 8 titration mode
Eight With power-off protection function
9.USB interface RS-232 Print interface, random matching special software by USB titration instrument. The interface can be connected to the PC machine, the computer can display real-time titration curve and its first and two derivative.
Edit and modify the convenient titration mode, and the results of statistics.
Ten Support to restore the factory settings
