PINPOINT Nitrate Monitor

They can make one for freshwater, anythings possible just give it a little time!

Hi Tony, while anything is possible, unfortunately, I don't think there will be a digital freshwater nitrate meter in the near future. There is simply not enough unit volume at $249 to make the project worthwhile. Let's see what John reports after his experiment. The answer may be to just add a tiny amount of salt to the freshwater sample.

I SPOKE WITH LOU AT THE FACTORY.....

1) i will try kosher cooking salt ( pure salt)
2) i will measure the salt level in the calibration fluids provided with the test unit and match it.


will post results.........
