Hanna HI782

[JuanJJ]

I have measured few times NO3 with de New Hanna HI782 and I'm seeing that the values are much higher than the Salifert and Nyos checkers.

Hanna HI782 --> 15.9
Salifert --> 9-10
NYOS --> 10.

Is somebody experimenting this behavior?

I find it so hard to differentiate between the colors of the nitrate tests as a lot of people do. My Hannah is in the ballpark is what I see by eye but definitely feel I can trust the Hannah more than my eye. Looking forward to seeing more on this baby as more and more people use it. So far very happy with mine

I agree with the above post, the checker has a +/- of 2ppm so your results are very close, if you also factor in the +/- of the salifert and Nyos test kits you will be near enough getting the same reading from all three.

I agree, those values are all identical within the range of errors associated with each test.

Fortunately, all of those values, from 9 ppm to 16 ppm are perfectly fine.
