Thank you for your comment GoVols. I don't want to go into too talking down about our competitors. We try to let our products speak for itself at ITS because there is nothing else like it. The number of parameters you can test for on one device versus buying multiple kits or devices truly is amazing. I will provide you with information regarding our photometer when it comes to nitrate and phosphate tests.
Phosphate-Range(0.02-2.5ppm) Accuracy(+or- 4%)
Nitrate-(3-100ppm)(+or-20%)
I hope you find this useful. Also you can refer to the tests and reagents tab on
