Drinking Water pH Test Kit
It is important to test the pH of every batch of ionized water to ensure you're getting the proper pH. The Hydrion concentrated pH indicator solution will give accurate pH readings from pH 1.0-11.0. Just put one drop of the indicator solution in the 4 ml vial with your sample solution to give a bright, easy-to-read color. Match the color directly to the laminated color chart for quick and easy pH measurement. Colors remain stable for delayed readings.
