Mene je zbunilo pa za neke slijedeće početnike... ;D
Kod nekih NO2 testova vrijednost 0.3 je granica OK područja (Tropical, Tetra), a kod testova nekih drugih proizvođača (JBL) je to već debelo u CRVENOM području!!
Evo zašto:
Correspondingly, both values (NO2 and NO2-N) can be converted into each other by simply multiplying or dividing them by 3.3; their relevance is absolutely identical. The factor results from the atomic weights of oxygen and nitrogen. Nitrogen is slightly lighter, so the nitrogen amount in the nitrite ion is a little less than a third.
Btw. Sera na ton karti ima i jedne i druge vrijednosti.
