Production introduction:
DDY - 2008 - j type automatic potentiometric titrator adopts mechanical and electrical integration structure design, completely controlled by the microcomputer control instrument, to realize the automation and visualization titration process and data processing. Choose different electrodes can be carried out: acid and alkali neutralization titration, precipitation titration, REDOX titration, complexometric titration, non-aqueous titration (such as the determination of basic nitrogen in petrochemical products, mercaptan sulfur, acid, alkali value) and so on the many kinds of titration, titration system adopts imported special material precise integration exchange units, configuration, prevent infiltration titration perchloric acid corrosion resistance, equipment is more reliable, longer service life and suitable for industry application. Features:
1. Visual 6 inches large screen LCD display, Chinese interface, the mouse operation, the man-machine dialogue mode.
2. The titration curve (E - V) and the first derivative curve (DE/DV) real-time display, straightforward titration process, automatic curve super world \ scrolling manually.
3. Automatic cleaning, automatic rehydration, automatic constant value add liquid.
4. Automatic end discrimination, automatic filtering false end point, can be manually delete false endpoint/add artificial discrimination, support for multiple end point titration.
5. The default initial dynamic volume (DET), when the bit amount when drop (MET), such as the preset destination potentiometric titration (SET), pH correction (CAL), pH measurement (MEAS).
6. The titration results, the titration curve (E - V, DE/DV) and complete titration data printing.
7. Play impedance input, electrode potential and stable and reliable.
8. Imported precise integration exchange Unit , allocation of anti osmosis titration head, perchloric acid corrosion resistance, equipment is more reliable, longer service life. Technical indicators:
