7.3.1. Functions titration solution
Selection of the titration acid and its concentration [mol/l].
- Default: HCL, H2SO4 and other
7.3.2. Parameters
- Titration speed
The titration speed can be inuenced by this factor.
It considers the various pH-changes for various concentrations of the titration
solutions and boric acids. If the factor is set to 1, a titration is done tted to a 2%
boric acid, which is titrated with a respective (0.1 mol/l) titration solution. If another
titration solution is selected, e.g. with a concentration of 0.5 mol/l. there is the
danger of uncontrolled over dosing with same titration functions. Here, the titration
speed can be adapted with the help of the factor.
Rule is: Factor > 1, titration speed is reduced
Factor < 1, Titration speed is increased
Calculation of titration speed
pHx = start continuous pumping in distilling mode
c = Concentration in mol/l
S = Titration speed

You can chose between 3 different tables or by selecting "Curve" work without
tables. Detailed information on how to work with titration tables is available in chap.
