Compact analysis set in carry-case for reliable determination of key parameters for water in scientific lessons which do not require detailed prior knowledge. The case contains all the necessary reagents and accessories. It can be used to determine the following parameters for natural water: ammonium-content, nitrate-content, nitrite-content, phosphate-content, pH value and overall hardness. There are enough resources for at least 50 investigations. Analysis can be carried out quickly and easily by comparing colors against a card template. Includes detailed instructions in German, English, French and Spanish.

Measuring ranges:

Ammonium: 0.2 - 3 mg/l NH₄⁺
Nitrates: 1 - 90 mg/l NO₃^-
Nitrites: 0.02 – 0.5 mg/l NO₂^-
Phosphates: 0.5 - 15 mg/l PO₄^3-
pH: 4.0 - 9.0

Water hardness: 1 drop of reagent = 1°dH (German degree – degree of general hardness)

Dimensions: approx. 38x30x11 cm³
