ePOOL® is a revolutionary accessory for your pool or spa that tests pH and chlorine levels and provides a constant water temperature readout. ePool will also measure bromine levels in spas and hot tubs. Measurements are taken by a sensor located within the floating sensor that remains in your water. Measurements are relayed to the receiver every 15 minutes and the receiver will alert you when the pH or the chlorine levels are out of range and need to be modified. ePOOL® is personalized to your pool or spa through the set up process, so it takes the guesswork out of pool maintenance. It tells you exactly what you need to keep your pool balanced, safe and healthy.
No test strips are needed for pH and chlorine levels, and it works on regular, salt water and mineral pools. Easy to set up and PC and Mac compatible. Patented technology. Requires four (4) AA batteries (included). Full replacement warranty-90 days.
Great Piece of Equipment Review by Brian I
Got pool chemistry close, entered data from pool store sample, monitor tells me when to put tablets in, when to add acid or alkalinity up, and how much. Can tell if pool temperature from desktop computer.
The only downside is the dongle always has to be plugged into a computer, and the software is resident on on PC at a time. If the dongle could be attached directly to my wireless router, this would be perfect. As it is, it's only great.
