MN VISOCOLOR® ECO test kit oxygen,1 – 10 mg/l O2

VISOCOLOR® ECO Oxygen • Colorimetric determination of oxygen • Oxygen determination according to Winkler: in alkaline solution dissolved oxygen oxidises manganese(II) ions to higher-valent manganese hydroxides. • In a strongly acidic medium these form manganese(III) ions which can be determined either titrimetrically or colorimetrically after addition of a colour reagent. Type: colorimetric test kit Range: 0 · 1 · 2 · 3 · 4 · 6 · 8 · 10 mg/l O2 Sufficient for: 50 determinations Shelf life at least: 1 year Sea water suitability: yes Detectable with PF-12: yes • The solubility of oxygen in water depends on the temperature, the pressure and the other components of the water. • The oxygen content of a water at the time of sampling is often quoted as the percentage of the possible saturation. • Please note: When ordering this test kit for the first time, you also need an oxygen bottle
