The Sutro Smart Monitor is a highly efficient device that tests your pool, hot tub or all season pool water three times a day using a professional-grade cartridge of reagents. These reagents are similar to those found in liquid water test kits, providing the most reliable and precise measurements available on the market.
The Sutro smartphone app generates daily reports that show your pH, free chlorine (or bromine), and alkalinity levels, and it recommends precisely what and how much of each water care chemical you should add.

Sutro is a smart system that will help you manage your pool (or spa). It's the simple, safe, and seamless way to measure, monitor, and get treatment recommendations to keep your water safe.
