![]() Anyone ever use the Hanna ultra low range phosphate colorimeter?
http://hannachecker.com/manuals/Phosphorus.pdf Looks pretty nifty and very useful for phosphate monitoring when running GFO. 0 to 0.2 ppm, +/- 0.01 ppm accuracy (not much better than a good test kit IMO, but convenient and you leave it to the meter to assign the number).
