Comes with two vials one at 0.0 that you put in first to calibrate the meter C1
Then you take second vial that comes preloaded with phosphate level at 1.00, add the little powder pack and mix. After the three minutes you get second reading C2 which in my case was bang on 1.00
If you want I can bring my calibrated meter over and we can test your water with both. If reading is the same then we know yours is accurate as well.
Let me know

What if the second reading is not 1.00? Is there a way to adjust it?
