Not sure if your ozonator is producing a sufficient level of ozone? This test kit is your solution!
The 30 Second Hot Tub Ozonator Test Kit includes; 2 pieces of specially sized tubing, ozone tester in glass, and testing instructions.
The purpose of this kit is to see if there is ozone present in the output stream of your ozonator. The extent to which the blue material turns white, will give you a good indication if your ozonator is producing enough ozone.
The kit provides a qualitative test for the presence of ozone, and does not quantify the amount of ozone produced. If the blue material turns white in 30 seconds (or mostly white), your ozonator is producing enough ozone. If the tester stays blue, it is time to replace your spa ozonator.
Once a blue ozone tester turns white, it can not be reused. If the blue material does not turn white, it can be reused again at a later time (store a good tester at room temperature and out of direct sunlight).
