I got my Hanna Nitrate HR checker today. Using it is very similar to the ulr phosphate checker, First you put in just tank water, then add reagent and shake for two minutes. You put it back and hold the button till the 7 minute timer starts.
Seems accurate. I tested two tanks and it matched the salifert tests I did yesterday on the same tanks.
