The Crystal Water Monitor Sensors will take readings of your pool or hot tub water 144 times per day. Our sensors will measure your pH, ORP and temperature.
If you are managing your pH and ORP with the Crystal Water Monitor, your Total Alkalinity, Calcium Hardness and Cyanuric Acid will rarely change from week to week. However we would like to see the direction those lesser important elements are headed, so we provide test strips to give us those readings monthly. Based upon all of these readings, we will give you calculated chemical actions to help keep your water balanced.
