It would still be nice to know if thery are online with the colour charts
though.

I don't think color accuracy of most printers would be good enough.

And just to be sure for Nitrates it is 5 drops of reagent 1 and 5 drops of
reagent 2 shake and then add 3 drops of reagent 3 and shake wait 5
minutes shake again and read off colur chart (thats of the top of my head
now I could be wrong!

That's right.

The nitrite test is just 5 and 5 (only 2 reagents ) Thats why i asked
previuosy if they are the same as the first two reagents in the Nitrate
test!

They're the same, so you could just use the one kit.
