Reagents for HI 775 and HI833xx - 25 tests

Magnesium Hardness Checker HC The hardness or hydrometric titer (TH) of water essentially corresponds to the presence of calcium and magnesium salts. It is directly linked to the geological nature of the terrain crossed. A calcareous soil will give hard water while a granite soil will produce rather soft water. The total hardness represents the sum of the calcium and...

Testeur d'eau SeaTest GH SeaTest GH water tester, description and features: Total hardness (GH) indicates the quantities of magnesium and calcium salts dissolved in water. These are directly responsible for a large number of physiological processes in plants and animals. They also...

Fresh water alkalinity photometer This measurement is important to define the corrosive characteristics of water, due mainly to hydroxide, carbonate and bicarbonate ions, and to anions which cause hydrolysis such as phosphates, silicates, borates, and the salts of some organic acids. Measuring alkalinity is essential when monitoring soil, drinking water...

Nitrates checker HI97728C reagent (100 tests)

Nitrates checker (up to 30,00 mg/L) Freshwater only! Nitrogen compounds such as nitrates result from the decomposition of micro-organisms present in the ecosystem. They are naturally present. Nitrates are largely ingested in the composition of fertilizers and are detected in the water of all agricultural regions. European standards allow a...
