Automatic laboratory potentiometric titration equipment/potential titrator
1. This potential titrator is integrated titration design and convenient and automatic titration system.
a) It has valved and integrated burette design which is convenient to replace avoiding mutual interference of different solutions in different titration.
b) It can automatically identify pH standard solution group (standard solution group1: 4.00pH, 6.86pH, 9.18pH; standard solution group2: 3.78pH, 7.00pH, 10.01pH) and has manual identification.
c) It supports to set system time, operator No., titrator type, titrator coefficient, stirring speed, manual temperature and potential zero-correction.
d) Titration end remind.
2. Accord with measuring information of GLP standard and make information more integrated
a) It can store 200 sets of titration results and a set of titration curve.
b) It supports to delete, consult, print and output data.
c) It can record titration model, titration type, titration start time, titration end time, operator, stirring speed, burette type, burette coefficient, titrant concentration, sample volume, terminal number and relevant concentration value.
3. Firmware version upgrade function, which decreases your titration cost and makes your operation more perfect
a) it can combine with automatic sampler to improve efficiency by software upgrade.
4. Titrator control method: dot-matrix LCD display, keys operation, Chinese software control simultaneously and respectively in computer.
5. It can display measuring methods, titration curve and measuring result.
6. It has pre-titration(dynamic titration), pre-end-titration, mode titration (providing two kinds of titration modes: a: HCl→NaOH (0.1mol/L); b. K2Cr2O7→Fe2+ (0.1mol/L))
7. It has blank titration, manual titration and pH measurement, supports specialized titration mode and allows users create 8 kinds of titration modes.
8. Electric-cut protection.
9. USB interface, RS-232 printing interface, assorted with specialized titration software randomly. It can combine PC by USB interface.
10. It supports to restore factory settings.
