Hanna PO4 Meter by SCOTT SAVADER

Experience Level: Intermediate

Comments: An electronic meter is a must if you want to measure PO4 levels below .25, which this does, but there is a disappointing variability in the results. Yesterday's measurements gave me 0.08 ppm followed by a second test giving a reading of 0.13. So if you can't handle a margin of error of +/- 0.05, then pass. Yes, I would recommend this product to my friends.

Comments: This is a great product. Ordinary test kits may be ok to use for finding out if you have a phosphate problem, but they just don't cut it when it comes to monitoring the low range levels of phosphate. There have been a few reports of people, including me, who have gotten bad batches of reagents causing inconsistent test results. Fortunately, Marine Depot took care of my issue, and now I'm getting very consistent results. This unit will also help me to determine when it's time to change the media in my phosphate reactor. Yes, I would recommend this product to my friends.
