Has anyone ever used a digital nitrate tester? Instead of the liquid test kits?
Nothing you said made any sense and did not help me. If this was a joke, then shame on you for spamming, if this is not a joke, then maybe pay attention before you reply to a post.I have searched that until the internet said "UNCLE" lol.
I'm guessing your having the same issue as everyone trying to decipher the color chart?
heres what you do.
1st a lil background,im a stroke victim which left me partially blind & almost completely color blind,so i have to have my wife read the samples.
One cant imagine the Chit storm that created when I was impatiently asking "WELL?"
make a trip to your local dollar store,and look for a pair of these.
the color you are looking for is Blue.
take your color chart with you and when you find the right pair the 10-20ppm and the 40-80 will stand out completly to make them easily readable.
hope that helps. Gg
