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 4 calibration solution 1 bag

pH 7 calibration solution

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...

pH computer-Set Microprocessor controlled pH monitor and controller The pH computer-Set utilises a modern microprocessor, which provides high precision measurement and control. The pH computer-Set is used to control precise values of pH in the aquarium or the Calciumreactor. The computer can switch up to 500 watts using the supplied external electrical...

pH controller (without probe) pH monitor and controller The pH controller is a precision instrument for controlling the pH value in aquaria. In combination with a CO2 system and a solenoid valve the pH can be maintained at a constant level, and the CO2 supply to aquatic plants or into a Calciumreactor can be controlled. The unit is supplied with a large LED...
