Ecotest Water

The AQUANAL®-Ökotest Water Laboratory contains six tests on substances dissolved in water. The tests can be performed simply in a short space of time with the help of the accompanying users’ instructions. The reagents are provided with a colour code for each test which corresponds to the anticipated colour produced in the particular test. The test result is determined from a colour chart. The individual reagents are developed such that they pose no threat to either the user or to environment. The entire set does not have to be marked in conformity with the Chemical Law. The AQUANAL®-Ökotest Water Laboratory is especially suitable for the private user, for example testing the quality of spring water, or for use in schools, such as a project week studying the water quality in local bodies of water.

The following substances to be found in water can be determined by the AQUANAL®-Ökotest Water Laboratory:

Ammonia (NH₄) is a nitrogen compound. It is produced in the decomposition of substances containing nitrogen (manure, humus) in low-oxygen conditions. Nitrogen is an indicator of water quality, too much of which can lead to a fast growth of micoorganisms and an imbalance in the water source.

Measurement range: 0.05 - 10 mg/l ammonia

Nitrate (NO₃) is not only a component part of manure containing nitrogen, but also a natural part of green plants. As rain water flows over the earth nitrate enters surface water and the ground water. A high nitrate concentration can lead to overferilisation and finally to the ”death” of a body of water.

Measurement range: 0 - 80 mg/l of nitrate.

Nitrite (NO₂) is a preliminary stage of nitrate, the only difference being one oxygen atom (O). Nitrite is an indicator of heavy contamination of a body of water. In large quantities, nitrite can pose a danger to humans, particularly infants, since it impedes oxygen flow in the blood (cyanosis).

Measurement range: 0.02 - 1.0 mg/l of nitrite

Phosphate (PO₄) can enter the ground water from fertilisers and washing and cleaning substances containing phosphate. Up to now phosphate has not displayed any harmful effects on health, although it promotes the growth of plants and, in high concentrations, can lead to an imbalance in a body of water.

Measurement range: 0.5 – 6. mg/l phosphate

pH value is a measure of the alkalinity or acidity of water. On the pH scale where a pH of 0 is strongly acidic, a pH of 7 is neutral and a pH of 14 is strongly alkaline, our drinking water should have a pH value between 6.5 to 8.5. It is interesting to take a pH reading at some time for soap solutions, vinegar and mineral waters.

Measurement range: 5.0 – 9.0

Total Hardness is a measure of the calcium and magnesium salts dissolved in the water. It is measured by the German hardness level (°d). The hardness is evident, for example, in the calcium deposit in a coffee machine.

Measurement range: 1 drop = 7.19 mg/l Calcium
