TEST KIT GUARDEX 4 IN 1

The Guardex 4-in-1 OTO Test Kit is used in residential pools for testing pH, Total Chlorine/Bromine, Acid Demand and Total Alkalinity with 1 ounce and .5 ounce reagent bottles. It does this by using a color comparator and a drop test to visually determine current levels of pH, chlorine, etc. Reagents are stored in a sturdy blue case and include 1 ounce bottles of Reagent Number 1 OTO Chlorine Indicator, Number 2 Phenol Red (pH indicator), and Number 3 Acid Demand Titrant. It also includes 1/2 ounce bottles of Number 4 Chlroine Neutralizer and 5B Total Alkalinity Indicator, as well as directions and testing tips.

Proper and frequent testing of pool and spa water is your first line of defense in protecting your family and your pool or spa. The ideal level of pH should be between 7.4 and 7.6. Chlorine residual should be between 1.0 and 3.0 ppm. Do not perform any tests if the chlorine level is above 3.0
