ELOS Expert line Test kit ( NH3/NH4)

[kwirky]

i've got an elos kH and an elos pH, and they're both excellent products. I'd say equal with salifert in quality of the chemicals. The pH colour chart is EXCELLENT, best I've ever seen. It's so good I just calibrate my pH monitor to whatever the Elos kit says. No guesswork ever, between colours.

Only complaint I have is the written instructions, and the diagrams on their little cards inside seem to contradict each other for some of the steps. Often time lengths are described by words such as "shortly" or "briefly", instead of telling me "a second or two" or "ten seconds" (like salifert does); I look at the diagram card, and it tells me to put all my drops in for titrating kh, THEN mix it for 30 seconds... lol

It's nice having the little ziplock bag inside though. Made me get ziplock bags outa the kitchen for all my salifert test kits
