10. kHLab Magnetic Stirrer Preparation
Make sure that inside the kHLab module test/mixing cylindrical chamber is a dedicated
water mixing magnetic stirrer bar/pellet (small white bar). That bar/pellet is necessary for
proper water sample mixing during perform tests. Also, connect the kHLab module to the
Kore 7th dosing station by using the dedicated 8-pin plug cable.
Important!
Due to its physicochemical properties, the pH probe will take some time
to stabilize and provide accurate/repeatable results. Consequently, it is
recommended that during the first days/weeks of using the pH probe, the
calibration procedure be carried out more frequently than recommended.
11. Reagent Solution Preparation
This device preparation step is very important. If the reagent dilution ratio is not correct,
the tested results may differ from the actual alkalinity levels. To obtain accurate results, we
strongly suggest using the digital scale for reagent dilution.
Important!
The 1000ml (2x500ml) of Concentrated Reagent included in the package
has to be diluted with RO/DI water (TDS=0) before use in 1:4 ratio.
EXAMPLE
: 100ml of concentrated reagent has to be added to 400ml of
RO/DI water (TDS=0).
Before beginning the reagent solution preparation steps, prepare two containers:
‒
Measuring Container
- must have a minimum of 100ml capacity for measuring
the correct amount of concentrated reagent and RO/DI water (TDS=0);
‒
Target Reagent Solution Container
- must have a minimum of 500ml capacity
for mixing concentrated reagent with RO/DI water (TDS=0).
Warning!
The pH probe must always be calibrated before using. Remove the clear
cap (small container) from the pH probe before starting the calibration
process and before use of the pH probe.
