This kit performs 6 different tests. Two test strips for each.
Iron content ( in ppm ), the pH level and the hardness ( in ppm and grains ), total alkalinity ( in ppm ), Nitrate and Nitritate ( as N ) in ppm.

Test includes instructions, color matching chart, and is very simple to use.
Measures pH ranging from 2 to 12,
Hardness between 0 - 1000 ppm ( up to 59 grains per gallon ),
Iron levels from 0 - 1 ppm.( low levels only, not for high iron testing ), Total Alkalinity up to 500 ppm, Nitrate to 50 ppm, and Nitrite to 3.0 ppm.

We will always be happy to help "interpret" your results. Just email them to us.
