Product Description

DSHJ-4B Automatic Coulometric Karl Fischer Titration
The main features
1. The integrated compact titration instrument design, convenient automatic titration systems
A) burette integration valve design, convenient replacement, effectively avoid the mutual interference of different titration using different solution problem
B) automatic identification pH standard liquid group, (the liquid group 1:4. 00 pH, pH 6.86, pH 9.18; the liquid group 2:3. 78 pH, pH 7.00, pH 7.00), at the same time support manual identification
C) support sets the system time, operator number, type of burette, burette coefficient, stirrer speed, manual, such as temperature, as well as the adjustment for potential zero value.
D) remind of titration end point
2. The measurement information in conformity with the GLP standard, the traceability information more complete
A) support the storage of 200 sets of the titration results and 1 set of titration curve
B) support data delete, check, print, or output
C) mode, the types of titration, full records titration titration end time, start time, titration coefficient of the operator, stirring speed, burette type, burette, the concentration of the titrant, sample volume, destination number, as well as the related density
3. The firmware version upgrade function, reduce the cost of your titration, let you more perfect operation
A) through the software upgrade, can connect to the automatic sampler, perfect efficiency
4.Titration instrument control mode: dot-matrix liquid crystal display, keystrokes, computer software in Chinese at the same time control or control respectively
5.Real-time display the relevant test method, titration curve, the measured results
6.A preliminary titration (dynamic titration), the default titration end point of titration, model (random provides two special patterns titration a. HCl and NaOH (0.1 mol/L), b. K2Cr2O7 - Fe2 + (0.1 mol/L).)
7.A blank titration, manual titration, PH measurement and various titration mode, support to generate special titration mode, allows the user to create up to eight kinds of titration mode
8.Has the power to protect function
9. The USB interface, print the RS - 232 interface, form a complete set of random special titration instrument software, through the USB interface can be connected PC, on the computer can be instantly titration curve and its first and second order derivative.
Convenient, edit and modify the titration mode and can be the result of statistics, etc
10.Support to restore factory Settings
