• One strip tests pH, alkalinity, hardness, nitrate and nitrite

Use for quick process checks and for clean water samples such as potable water. Strips test alkalinity as defined by calcium hardness and total hardness as defined by both calcium and magnesium carbonate concentration.

Simply swirl the strip in your sample three times, and place or hold the strip on a level surface. After one minute, compare the results on the strip to the color chart on the bottle.
