Hanna phosphate Checker calibration

Bogartus · Mar 24, 2018

So my Hanna phosphate Checker reads my phosphates .07 to .09 Paso Robles. Then when I use my API tester it looks like it's in about .02 can these Hanna Checkers get out of calibration? And if so how do you calibrate them?

If im not mistaken the hanna phosphate checker will have a +- 4 reading, which if it does then your good and pertty much on point. They say if your really want a more on point reading then better to go with the phosphorus checker. Dont quote me on it but there is a video by BRS on the phosphate hanna checker.

Thanks I watched their videos and they were helpful. I also watched videos on the Triton testing, I have heard of it, but now I am going to do it !
