This is a Taylor Combination Drop Test for Hydrogen Peroxide 5 ppm (Iodometric) and pH (6.8-8.2) Midget Comparator (phenol red) Test Kit. The K-9061 Kit tests for Hydrogen Peroxide using a drop test system and iodometric method/chemistry. It also will test for pH using a midget comparator.
Some swimming pools do not use chlorine but a combination of ultraviolet disinfection with hydrogen peroxide. So testing for hydrogen peroxide would be an important test for individuals using this method for sanitizing their pools or spas. Testing your swimming pool pH is one of the most important water chemical tests for water balance.
