digital meters

[Bc chick]

is there a digitalmeter that tests for ammonia, nitrates and nitrites? do you have to buy them separately?

Separate. I just tried looking. Can't wait for an inexpensive one to come out.

All three separate? That stinks. How do these work? Anyone try?

There are digital ones for nitrate, I'll get one as soon as I win the lottery.

Hanna has some digital testers that are more accurate than drops, pricey though and you still need to add reagent to a little bottle.

For ammonia...

Dang.. I just saw that the Pinpoint nitrate tester is for salt water only. It looks like you would need to spent a fortune on a colorimeter to get accurate nitrate measurements in freshwater.
