I have the Hanna nitrate HR and it been reading all sorts of stuff. For example just tested. First time read 8.4 and second time read 32.1. Tested at the same time right after. What do I do about this?

did it go into countdown mode the first time?.......
mine does this all the time, skips the countdown and goes straight into a number.....I think its user error (at least on my part)

Nope, definitely counted down. Was sitting here watching and plus have done it multiple times like this. Been doing it for a month.

Then you have two sources left. Bad device or user error
What are you using to measure your water volume? And how are you getting the reagent out of the wee pouch?

Im not using anything filling it up to then white line as always. And getting the powder out of pouch. I was thinking bad device.Then you have two sources left. Bad device or user error

I think so too..
it's a hard one to do wrong, I do use an adjustable pipette for mine though to make sure amount of water is 100% accurate and consistent every time.As for the powder, make sure you get it all out- every time.
possibilities:
smudges; make sure vial is oriented lettering front
