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...

pH 7 calibration solution

HOBBY Humin superactiv 1.200 ml The optimal additive of trace elements, plant hormones and humic acids, especially for tropical, subtropical but also local fish that need particularly neutral to acidic (soft) water. You will achieve stable pH levels over a longer period of time. The use of the filter material in the HOBBY Nylon pouch is convenient...

HOBBY Natalit 3 l Aquarium soil wash. Promotes root formation. Color wise, ideal contrast to fish and plants.

HOBBY Aqualit 12 l, approx. 8 kg Lime-free substrate with the most important trace elements for healthy root formation and strong plant growth. The granular composition and porosity are ideal for oxygen circulation in the soil. With vegetative factor F17.

HOBBY Aqualit 3 l, approx. 2 kg Lime-free substrate with the most important trace elements for healthy root formation and strong plant growth. The granular composition and porosity are ideal for oxygen circulation in the soil. With vegetative factor F17.

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...
