4. 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 of SUPER Concentrated Reagent included in the package
has to be diluted with RO/DI water (TDS=0) before use in 1:49 ratio.
EXAMPLE: 100ml of concentrated reagent has to be added to 4900ml of
RO/DI water (TDS=0).
SUPER Concentrated
Before beginning the reagent solution preparation steps, prepare two containers:
‒ Measuring Container
the correct amount of concentrated reagent and RO/DI water (TDS=0);
‒ Target Reagent Solution Container
for mixing concentrated reagent with RO/DI water (TDS=0).
To prepare ready to use 500ml of reagent solution follow these steps:
1) Prepare an empty
2) Place the
Measuring Container
3) Turn ON the digital scale.
4) Wait a few seconds and then zero-out the digital scale by clicking (T) Tare button.
Before starting reagent measurement, the digital scale must show 0.00 g on the
LCD display.
5) Make sure that the digital scale is showing [g] as the weight unit. If not then start
clicking (M) button until you see [g] gram unit on the display.
6) Measure exactly 10g of reagent (from a 1000ml bottle with SUPER concentrated
reagent included in the package).
7) Pour out the measured amount into the
8) Place the empty
9) Wait a few seconds and then zero-out the digital scale by clicking (T) Tare button.
10) Pour in exactly 490g of RO/DI water into the
measured RO/DI water into the
11) After adding the whole (10ml of SUPER concentrated reagent and 490ml of RO/DI
water) mix everything by shaking the
times.
The prepared reagent solution is ready for use. We recommend preparing no more than
5000ml of ready to use
days of performed Alkalinity tests (12 tests/day).
