Safety precautions
CAUTION
Reagents are formulated exclusively for chemical analysis and must not be used for
any other purpose. Reagents must not get into the hands of children. Some of the
reagents contain substances which are not entirely harmless environmentally. Be
aware of the ingredients and take proper care when disposing of the test solution.
CAUTION
Please read this instruction manual before unpacking, setting up or using the
photometer. Please read the method description completely before performing
the test. Be aware of the risks of using the required reagents by reading the MSDS
(Material Safety Data Sheets). Failure could result in serious injury to the operator or
damage to the instrument.

1.1 Methods
The precision of Lovibond® Reagent Systems (tablets, powder packs and tube tests) is identical
to the precision specified in standards literature such as American Standards (AWWA), ISO
etc.
Most of the data referred to in these standard methods relates to Standard Solutions. Therefore
they are not readily applicable to drinking-, boiler- or waste-water, since various interferences
can have a major influence on the accuracy of the method.
For this reason we don’t state such potentially misleading data.
Due to the fact that each sample is different, the only way to check the tolerances (‘precision’)
is the Standard Additions Method.
According to this method, first the original sample is tested. Then further samples (2 to 4) are
taken and small amounts of a Standard Solution are added, and further results are obtained.
The amounts added range from approximately half, up to double the amount present in the
sample itself.
These supplementary results make it possible to estimate the actual concentration of the
original sample by comparison.
Literature
The reagent formulations are based on internationally recognised test methods. Some are
described in national and/or international guidelines.

5 – 200 mg/l CaCO3
1. Fill a clean vial (24 mm Ø) with 10 ml of the water sample,
close tightly with the cap.
2. Place the vial in the sample chamber making sure that
the marks are aligned.
3. Press ZERO key.
4. Remove the vial from the sample chamber.
5. Add one ALKA-M-PHOTOMETER tablet straight
from the foil to the water sample and crush the tablet
using a clean stirring rod.
6. Close the vial tightly with the cap and swirl several times
until the tablet is dissolved.
7. Place the vial in the sample chamber making sure that
the marks are aligned.
8. Press TEST key.
The result is shown in the display as total Alkalinity.
