Environmental analysis case
A great number of substances which are important to the environment may
be analysed with the aid of test sticks in a semi-quantitative manner. The
test sticks may be used as an economical alternative, supplementing measurements
made with electronic measuring instruments. The test sticks are
easy to use and rapidly provide useful results.
The analysis case offers a versatile selection of test systems, matched specifically
to the treatment of ecological topics.

Analysis case for ecological tests
This low-cost, portable analysis kit permits determination of the most
important substances and parameters in water with adequate accuracy
using colorimetric and titrimetric testing aids.
The case can also be used by students or lay persons thanks to cards with
pictogram representations. The concentrations of a sample can be found
and read off easily by sliding the comparator. As measurements are conducted
using two cells (sample cell and reference cell), turbidity and
discolorations of the sample are compensated and thus cannot falsify the
measuring results. An undiluted sample can be used in most cases.
The set contains no toxic chemicals. The reagents are sufficient for 50 to
400 tests, depending on the type. Replacement testing aids are also
available individually.
The following tests can be conducted using the analysis case
