The Wireless Pool Chemical Monitoring System.

This is the wireless monitoring system that constantly checks your swimming pool¿s chemical condition 24 hours a day, automatically notifying you when to add chlorine to your pool, without the need for you to manually check or measure. It uses a remote floating pod that contains sensors for water temperature, pH, and chlorine level, which transmits its data wirelessly to the display. The sensor pod floats freely in your pool and takes measurements at the same 18" depth recommended by the Association of Pool and Spa Professionals. Your pool's pH level is measured based upon the total pool volume that you enter on the display, so the system tells you when to add chemicals to bring your pH near a balanced 7.2 reading (a chlorine generator is required for total alkalinity test). The sensor pod and display can communicate up to 150' away from each other, so you don't have to step outside each time you want to check on your pool. The sensor pod and one D battery provide up to a year of operation before requiring replacement, and the display plugs into AC. Sensor pod 24" H x 8" W x 4" D. Display 4 1/2" L x 4 1/2" W x 1 1/2" D.
