Volume increment
Small volume increments are used for the determination of blank values or
for very asymmetrical curves. A good guideline is 1/20 of the expected EP
volume. For steep jumps the volume increment should tend toward 1/100
and for flat jumps toward 1/10 of the EP volume. Small volume incre-
ments are used for determining blank values or with very asymmetrical
curves. The accuracy of the evaluation cannot be increased by using
smaller increments as the measured value alterations between two mea-
suring points are then of the same order of magnitude as the noise.
Titrando, 855
Input range
0.0001 - 9.9999 mL
Default value 0.05 (slow), 0.10 (optimal), 0.20 (fast) mL
Titrino
Input range
0.001 - 9.999 mL
Default value 0.05 (slow), 0.10 (optimal), 0.20 (fast) mL
Dosing rate
Speed at which the volume increments are added. The maximum dosing
rate depends on the cylinder volume of the exchange unit or dosing unit
used.

Input range
0.01 - 166.00 mL/min
Selection maximum
Default value maximum
Titrino
Input range
0.01 - 150.00 mL/min
Selection maximum
Default value maximum
Temperature
Temperature
Manually entered titration temperature. If a temperature sensor is con-
nected and the Temperature measurement is set on the General/
Hardware tab under Sensor to automatic or continuous, then the
temperature will be measured continuously. This value is used for temper-
ature correction in pH measurements.

Input range
-20.0 - 150.0 °C
Default value 25.0 °C
