Need a accurate nitrate test for colorblind people

[Kershaw]

I currently use elos because it is available every where. But I can't see the color. All the shades look the same!!well I can see the shades on card but the reagent is hard to see. So dose any one know one that is dummy proof.

Ditto! I'm using RedSea Pro and it all looks the same to me, just darker or lighter which I thought I could work with until my kids told me my readings didn't look right to them.

I'd need a Hanna like checker to result a number [emoji6]

Yea I have the Hanna for phosphate. It makes life easier. I don't think they have nitrate though.

I'm sure there are exceptions but as far as I know all of the hobby nitrate kits use the same test procedure, so they end up with the same colors.

$0.02 I'll be keeping my eyes out for an exception!

Just Hopping there is a kit that shows better contrast
