in order to improve the Test Kit range, to match the request of the more demanding reef-lovers, we have significantly increased the resolution of the NO3 test kit.
Attached a picture of the old color chart and the new one.
As you can realize, with the new color chart the color is more intense at similar value giving then the possibility to have a much higher resolution.
Very low concentration of NO3 (1 - 5 ppm) are now readable
making our test one of the most precise on the market.
Sure you will appreciate this.
