Temperature
compensation
The mobility of ions in water increase with higher temperature which
enlarges the conductivity. Therefore, the temperature is measured si
-
multaneous by an integrated Pt1000 temperature sensor and the
conductivity is compensated to 25 °C. Several temperature compen
-
sation curves, designed for different water compositions, can be cho
-
sen.
After cation exchanger (cation conductivity), the temperature com
-
pensation curve strong acids has to be set.

Conductivity, PPChem (2012).
Standard
Temperature
The displayed conductivity value is compensated to 25 °C standard
temperature.
Operation
The sample flows via the sample inlet [G] through the flow regulating
valve [C], where the flow rate can be adjusted, into the flow cell block
[B].
With the first conductivity sensor [A] the specific conductivity of the
sample is measured. Then the sample is led through the cation ex
-
changer bottle [M] where all alkalization agent is eliminated. After
-
wards the cation conductivity of the sample is measured with the
second conductivity sensor [H].
The sample leaves the measuring cell via flow meter and the sample
collector [J] and flows into the pressure-free sample outlet.
The temperature is measured with the temperature sensors integrat
-
ed in the conductivity sensors.
Pre-rinse
Option
The AMI Deltacon Power with pre-rinse option allows fast replace
-
ment of the cation exchanger because the resin is pre-rinsed. Pre-
rinsing has the effect to remove disturbing contaminations contained
in the resin, which may cause incorrect measuring values. The de
-
aeration of the resin vessel is done automatically.
If the pre-rinse option is installed, the sample flows via flow meter
through the per-rinse inlet [D] into the second cation exchanger bot
-
tle [F] and from there via pre-rinse outlet [E] through the sample col
-
lector [J] into the waste funnel.
The cation exchanger bottles are vented via two small tubes which
are connected to the flanges [K] and [L].
Correction or
calibration
Not necessary.
Auto zero is done automatically each day at 0:30 at night.
